What is a triangle?A triangle is a 2-D figure with three sides and three angles.
The sum of the angles is 180 degrees.
We can have an obtuse triangle, an acute triangle, or a right triangle.
We have,
We can use trigonometry to solve this problem.
Let's start by finding the length of BC.
sin(30°) = BC/AC
sin(30°) = BC/10
BC = 5
Now, we can use the Pythagorean theorem to find the length of AB.
AB² = AC² - BC²
AB² = 10² - 5²
AB² = 75
AB = 5√3
Therefore,
The length of side AB is 5√3.

3x - 11 > 7x + 9
⇔ -11 - 9 > 7x - 3x
⇔ - 20 > 4x
⇔ -20/4 > 4x/4
⇔ - 5 > x
⇔ x < - 5
The solution to the inequality 3x - 11 > 7x + 9 is x ∈ (-∞, 5) the graph is shown in the picture.
What is inequality?It is defined as the expression in mathematics in which both sides are not equal they have mathematical signs either less than or greater than known as inequality.
It is given that:
The inequality is:
3x - 11 > 7x + 9
After simplification:
3x - 7x > 9 + 11
-4x > 20
-x > 5
Multiplying by a negative sign on both sides:
x < -5
The number line can be defined as the representation of the numbers on a straight line that goes infinitely on both sides.
After plotting on the number line:
x ∈ (-∞, -5)
Thus, the solution to the inequality 3x - 11 > 7x + 9 is x ∈ (-∞, 5) the graph is shown in the picture.

Now choose to points on the line to use the slope formula.
(0,15) and (3,13).
Slope formula: [tex]\frac{y2-y1}{x2-x1}[/tex]

For the first picture determine the equation of the parabola shown in the diagram in vertex form and for the second picture determine the equation of the parabola shown in the diagram in factored form.
Answer:
see explanation
Step-by-step explanation:
the equation of parabola in vertex form is
y = a(x - h)² + k
where (h, k ) are the coordinates of the vertex and a is a multiplier.
here (h, k ) = (3, 1 ) , then
y = a(x - 3)² + 1
to find a substitute any other point on the graph into the equation.
using (0, 7 )
7 = a(0 - 3)² + 1 ( subtract 1 from both sides )
6 = a(- 3)² = 9a ( divide both sides by 9 )
[tex]\frac{6}{9}[/tex] = [tex]\frac{2}{3}[/tex] = a
y = [tex]\frac{2}{3}[/tex] (x - 3)² + 1 ← in vertex form
------------------------------------------------------
the equation of a parabola in factored form is
y = a(x - a)(x - b)
where a, b are the zeros and a is a multiplier
here zeros are - 1 and 3 , the factors are
(x - (- 1) ) and (x - 3), that is (x + 1) and (x - 3)
y = a(x + 1)(x - 3)
to find a substitute any other point that lies on the graph into the equation.
using (0, - 3 )
- 3 = a(0 + 1)(0 - 3) = a(1)(- 3) = - 3a ( divide both sides by - 3 )
1 = a
y = (x + 1)(x - 3) ← in factored form

The lengths of two sides of a parallelogram are 5x + 4 and 2x + 3y. Identify an expression for the perimeter of the parallelogram.
Answer: 2(7x + 3y + 4) [unsimplified] or 14x + 6y + 8 [simplified]
Step-by-step explanation: The perimeter of a parallelogram is 2 * (the two sides.)
Adding 5x + 4 and 2x + 3y, we get 7x + 3y + 4 by combining like terms in the x terms.
Now, we multiply by 2. This is 2(7x + 3y + 4) or 14x + 6y + 8
The length of a rectangle is increased by 25% , but the width of the rectangle is decreased by 25%. By what percent was the rectangle's area decreased
The rectangle's area decreased by 19%.
Length = L
Breadth = B
Original area = L x B
New area = A = L x (1 + 25%) x B x (1 - 25%)
A = L x B x 0.25 x 0.75 = L x B x 1.05
Therefore the area of the rectangle has decreased by 19%.
To find the location of a rectangle, multiply its width by means of its height. If we understand the sides of the rectangle which are different lengths, then we have each the height and the width.
The perimeter P of a rectangle is given through the system, P=2l+2w, wherein l is the period and w is the width of the rectangle. The area A of a rectangle is given by means of the method, A=lw, in which l is the duration and w is the width.

Using the mid-point concept, the set of points that has midpoint B(-41,23) is: G(10,10) and H(-92,36).
What is the mid-point concept?The mid-point between two points is the halfway point between them, and is found using the mean of the coordinates.
In this problem, we have that:
The mid-point is B(-41,23).The other points are G(10,10) and H(x,y).Hence the coordinates of H are found as follows:
[tex]-41 = \frac{10 + x}{2}[/tex]

The figure shows a circle circumscribed around a triangle.
Triangle U T V is inscribed within a circle. A point is at the center of the triangle. Lines are drawn from the points of the triangle to the point in the middle. Lines are drawn from the point in the middle to the sides of the triangle to form right angles.
What is constructed first when creating the circle?
perpendicular segments to the vertices of the triangle
perpendicular bisectors of the sides of the triangle
angle bisectors of each angle of the triangle
the incenter of the triangle
Option B is right perpendicular bisectors of the sides of the triangle
What circumcircle?If we draw a circle through all the vertices of a triangle then the circle obtained is the circumcircle of the given triangle. We have in a triangle there are some properties inherent.
One is the perpendicular bisectors of all sides are concurrent. These three concur at a point called the circumcentre of the triangle.
When we draw a perpendicular bisector for a side AB, we get that all points on the perpendicular bisector are equidistant from A and B.
When we take the point of intersection of the perpendicular bisector of AB and BC, we have the intersecting point S(say) is equidistant from A and B and also from B and C
In short, this is equidistant from all 3 vertices and hence is the centre of the circumcircle of triangle ABC
Therefore Option B is right perpendicular bisectors of the sides of the triangle.

⇔b² = 20
⇔ b = √20 (and not b= -√20 because b ≥ 0)
Answer:
b = [tex]\sqrt{20}[/tex]

6² = 4² + b²
