8p + 3q - 18 when p = 1/2 and q = 7
You are given that p is equal to 1/2 and q is equal to 7, so plug these values into p and q in the expression to find your answer.
Rewrite your expression to include the values of p and q plugged in. Your expression should look like:
8(1/2) + 3(7) - 18
According to PEMDAS, multiplication should be solved first before doing subtraction, so multiply 8 by 1/2 and 3 by 7. Rewrite your expression; your expression should look like this:
4 + 21 - 18
According to PEMDAS, addition and subtraction should be solved from left to right; they are not prioritized. So solve the expression from left to right and then you will have your answer.
4 + 21 = 25
25 - 18 = 7
Your answer is 7.
The measure of both angles are 112.5 and 68.5 degrees
<h3>Complementary angles</h3>
The sum of two complementary angles is 90 degrees.
If two angles are complementary, then;
x + y = 90
x = 90 - y..........1
where x and y are the angles
If two times the measure of one is equal to 40% of the measure of the other then;
2x = 0.4y ............2
Substitute equation 1 into 2
2(90-y) = 0.4y
180 - 2y = 0.4y
180 = -0.4y + 2y
1.6y = 180
Divide both sides by 1.6
1.6y/1.6 = 180/1.6
y = 112.5 degrees
For the other angle
x= 180 - y
x = 180 -112.5
x = 68.5 degrees
Hence the measure of both angles are 112.5 and 68.5 degrees

x = 60
x and 60 are alternate angles and congruent, thus
x = 60
Answer:
They are congruent, this is because both shapes are the same size and have the same angles as show with the lines at the edges. I believe it's AAS
