Question

Given parallelogram ABCD, find the lengths and angles required.

Find the value of x and the lengths of sides AB and CD.

Find the value of y and m
Question is above as an image

Answer 1

See below

Explanation:

No actually the top is kinda of wrong. To find the angles I think you do this...

(2y+50) + (3y+40)=180

5y+90=180

5y=90

y=18

Then you plug it in the equations...

Answer 2

x = 3, line AB = 17 , and line CD = 17

y = 10, angle A = 70, and angle D = 70

Explanation:

well since their the same length you can put them equal to each otheir

5x + 2 = 8x - 7

subtract 5x by both sides to get --> 2 = 3x -7

add 7 to both sides and get --> 9 = 3x

divide 3 by both sides to get x = 3

now plug it back in each equation we started with and get you answers

Same steps for y but different equations
