Question

Find x and y !

pls help giving 50 points !!

Answer 1

Answer = X=35 and y=20


C+2y =75
X + 2y+ 3x =180
First solve for 2y and then substitute and you get 35 after that u plug it into the second one and u get 20

Answer 2

y = 20°

x = 35°

Step-by-step explanation:

Equation's:

1) 2y + x + 105° = 180°

2) 3x + x + 2y = 180°

Make y subject in equation 2

3x + x + 2y = 180

4x + 2y = 180

2y = 180 - 4x

y = 90 - 2x

Insert this into equation 1

2(90 - 2x) + x + 105° = 180°

180 - 4x + x + 105 = 180

-3x = -105

x = 35°

Find value of y

y = 90 - 2x

y = 90 - 2(35)

y = 20°
