Question

In this parallelogram, the measure of 12 years ago

Answer 1

let x = measure of angle A, y = measure of angle B

<B is twice as big as <A, so we know that y = 2x

the two angles are supplementary, so x+y = 180

Answer 2

x+y = 180

x+2x = 180

solve for x, then use this to find y

Answer 3

?

Answer 4

these two angles are supplementary

Answer 5

okay i get tht

Answer 6

so if angle A is x, and angle B is y, then x+y = 180

Answer 7

B is twice as big as A

so

angle B = 2*(angle A)

y = 2x

Answer 8

so

x+y = 180

x + 2x = 180 ... plug in y = 2x

3x = 180

x = ???

Answer 9

60

Answer 10

y = 2x

y = 2*60 ... replace x with 60 (since x = 60)

y = 120
