Answers
Answer:
Part A:
1, 4, 5, and 8 = 55 degrees.
3, 2, 6, and 7 = 125 degrees.
Part B:
I know that angle 1 is 55 degrees so angle 7 would be 125.
I know that angle 1 is 55 and to get angle 2, both angles should add up to 180 so 180 - 55 is 125, that is how I find angle 2 = 125 degrees.
Step-by-step explanation:
This is what I wrote, I hope it helps and tell me if I am wrong but I think it is right.
Have a Meowgical day!
Part A:
The values of the angles are:
∠1 = 55
∠2 = 125
∠3 = 125
∠4 = 55
∠5 = 55
∠6 = 125
∠7 = 125
∠8 = 55
Part B:
∠1 and ∠7 are exterior angles on the same side.
∠1 and ∠2 form a straight angle.
We have,
Part A:
From the figure,
∠1 and ∠5 are corresponding angles.
So,
∠1 = ∠5 = 55
And,
∠1 and ∠8 are alternate exterior angles.
∠1 = ∠8 = 55
And,
∠1 and ∠4 are vertical angles.
∠4 = 55
And,
∠5 and ∠8 are vertical angles.
∠5 = 55
Now,
∠1 and ∠2 form a straight angle.
This means,
∠1 + ∠2 = 180
∠2 = 180 - 55
∠2 = 125
And,
∠5 and ∠6 forms a straight angle.
This means,
∠5 + ∠6 = 180
∠6 = 180 - 55
∠6 = 125
Now,
∠2 and ∠3 are vertical angles.
∠6 and ∠7 are vertical angles.
This means,
∠3 = 125
∠7 = 125
Part B:
∠1 and ∠7 are exterior angles on the same side.
This means,
∠1 + ∠7 = 180
Substituting the values.
55 + 125 = 180
180 = 180
This is true.
And,
∠1 and ∠2 form a straight angle.
This means,
∠1 + ∠2 = 180
55 + 125 = 180
This is true.
Thus,
The values of the angles are:
∠1 = 55
∠2 = 125
∠3 = 125
∠4 = 55
∠5 = 55
∠6 = 125
∠7 = 125
∠8 = 55
And,
∠1 and ∠7 are exterior angles on the same side.
∠1 and ∠2 form a straight angle.

What is the equation of the line perpendicular to the line y = 2x + 3 with a y-intercept of -6
Answers
Answer:
y = -¹/₂ x - 6Step-by-step explanation:
Two lines are perpendicular if the product of theirs slopes is equal -1:
y=m₁x+b₁ ⊥ y=m₂x+b₂ ⇒ m₁×m₂ = -1
y = 2x + 3 ⇒ m₁=2
2×m₂ = -1 ⇒ m₂ = -¹/₂

What is Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
We have 10 hats and 20 masks were sold for $30.
and, 8 hats and 10 masks were sold for $18.
let the cost of one hat be H and cost one Mask be M.
So, the system of Equation we get
10H + 20M = 30..........(1)
8H + 10M = 18...........(2)
Solving the above equation we get
10H - 16H = 30 - 36
-6H = -6
H = 1
and, 10 + 20M= 30
20M= 20
M= 1

A rectangular book measures 4 x 7. What is the length of its
diagonal?
Answers
A rectangular book measures 4 x 7, the length of its diagonal is √65.
Pythagorean theorem states that in a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides.
In mathematical terms, if a and b represent the lengths of the two shorter sides (also known as legs) of a right triangle, and c represents the length of the hypotenuse, then the Pythagorean theorem can be expressed as:
a² + b² = c²
Given:
Base = 4
Length = 7.
To determine the length of diagonal by using Pythagorean theorem.
Diagonal² = Base² + Length²
Plugging the values in Pythagorean theorem.
Diagonal² = 4² + 7²
Diagonal = √(16 + 49) =√65.
Therefore, the length of diagonal of book is √65.

AB = 6√2
CD =3√2
The area is half the product of the base (AB) and height (CD) so is ...

I have 10 goats, n of which are male. I need to choose 2 of them to make a casserole.
The probability both of my choices are male is 2/15
Use the information to form an appropriate quadratic equation N square + an + b = 0, specifying the constants a and b.
Answers
Answer: There are 4 male goats.
Step-by-step explanation:
We know that n of the 10 goats are male.
The probability that in a random selection, the selected goat is a male, is equal to the quotient between the number of male goats (n) and the total number of goats (10)
The probability is;
p = n/10
Now the total number of goats is 9, and the number of male goats is n -1
then the probability of selecting a male goat again is:
q = (n-1)/9
The joint probability (the probability that the two selected goats are male) is equal to the product of the individual probabilities, this is
P = p*q = (n/10)*((n-1)/9)
And we know that this probability is equal to 2/15
Then we have:
(n/10)*((n-1)/9) = 2/15
(n*(n-1))/90 = 2/15
n*(n-1) = 90*2/15 = 12
n^2 - n = 12
n^2 - n - 12 = 0
This is a quadratic equation, we can find the solutions if we use Bhaskara's formula:
For an equation:
a*x^2 + b*x + c = 0
The two solutions are given by:
[tex]x = \frac{-b +- \sqrt{b^2 - 4*a*c} }{2*a}[/tex]
For our case, the solutions will be:
[tex]n = \frac{1 +- \sqrt{(-1)^2 - 4*1*(-12)} }{2*1 } = \frac{1+- 7}{2}[/tex]
The two solutions are:
n = (1 - 7)/2 = -3 (this solution does not make sense, we can not have a negative number of goats)
The other solution is:
n = (1 + 7)/2 = 4
This solution does make sense, this means that we have 4 male goats.

y = 5
__
b) The graph is a straight line through the origin, so the equation is that of a proportion:
y = kx . . . . . for some constant of proportionality k

c) The graph has a rise of 3 units for each run of 1 unit, so the slope is ...
