Answers
Answer:
AB ≈ 8.86 cm
Step-by-step explanation:
Using the sine ratio in the right triangle
sin41° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{AB}{BC}[/tex] = [tex]\frac{AB}{13.5}[/tex] ( multiply both sides by 13.5 )
13.5 × sin41° = AB , then
AB ≈ 8,86 cm ( to 3 significant figures )
Answer:
8.87
Step-by-step explanation:
use the sin law for right triagles sin(θ)= opposite/hypotenuse so
sin(41)=(AB)/13.5
13.5×sin(41)=AB
8.87=AB

what is a factor for -20?
Answers
Answer:
1 ,2,4,5,10,-1,-2,-4,-5,-10,20
Answer:
factors are 2 and 5.
Step-by-step explanation:
Factors are numbers which you can multiply together to get another number. For Example : The numbers 2 and 3 are factors of 6 because 2 x 3 = 6. A number can have many factors! Example : 2 and 4 are factors of 8, because 4 x 2 = 8. Also 1 and 8 can also be factors of 8, because 1 x 8 = 8.
on prime factorization, we get the factors of 20 as,
2 x 2 x 5 = 20.
Essentially, to factor a negative number, find all of its positive factors, then duplicate them and write a negative sign in front of the duplicates. For instance, the positive factors of −3 are 1 and 3.
-2 x 2 x 5 = -20
2 x 2 x -5 = -20

You can see that there’s a right angle on the right side of the triangle.
Or, if you want to be more specific:
Since two triangles are congruent,

The true statements of the angles of the parallel lines are
a) m∠1 = m∠8
b) m∠6 = m∠7
c) m∠4 + m∠6 = 180°
d) 180° - m∠7 = m∠9 + m∠10
What are Parallel Lines Cut by Transversal?Straight, equally spaced lines that never cross each other and are on the same plane are called parallel lines. The angles that are created when any two parallel lines are intersected by a line (referred to as the transversal) have a relationship. Corresponding angles, Alternate Interior Angles, Alternate Exterior Angles, and Consecutive Interior Angles are some of the several pairs of angles that are created at this intersection.
Corresponding angles
When two parallel lines are intersected by a transversal, the corresponding angles have the same relative position
Alternate Interior Angles
Alternate interior angles are formed on the inside of two parallel lines which are intersected by a transversal.
Alternate Exterior Angles
The pairs of angles formed on either side of a transversal that divides two parallel lines are known as alternate exterior angles.
Consecutive Interior Angles
When two parallel lines are cut by a transversal, the pairs of angles formed on the inside of one side of the transversal are called consecutive interior angles or co-interior angles.
Given data ,
The true statements are
a) m∠1 = m∠8 ( alternate exterior angles )
b) m∠6 = m∠7 ( vertically opposite angles )
c) m∠4 + m∠6 = 180° ( co-interior angles are supplementary )
d) 180° - m∠7 = m∠9 + m∠10 ( triangle exterior angle theorem )
Hence , the angles of the parallel lines are solved

Plsssss helpppppppppp meeeeeeeeee
Answers
Answer:
x = 14, y = 37
Step-by-step explanation:
The angle vertical to (9x + 12 )° and 3x are same- side interior angles and are supplementary, sum to 180°, then
9x + 12 + 3x = 180
12x + 12 = 180 ( subtract 12 from both sides )
12x = 168 ( divide both sides by 12 )
x = 14, so
3x = 3 × 14 = 42
3x and 4y - 10 are adjacent angles and supplementary, then
3x + 4y - 10 = 180
42 + 4y - 10 = 180
4y + 32 = 180 ( subtract 32 from both sides )
4y = 148 ( divide both sides by 4 )
y = 37

After solving the equation, the value obtained for x is equal to 1.
What is an equation?Equations are mathematical expressions that have two algebra on either side of an equal (=) sign. The expressions on the left and right are shown to be equal to one another, demonstrating this relationship. L.H.S. = R.H.S. (left-hand side = right side) is a fundamental simple equation.
As per the given equation in the question,
13x - 12 = 7x - 6
13x - 7x = -6 + 12
6x = 6
x = 6/6
x = 1
Therefore, the value obtained for x will be equal to 1.
