Question

Find the value of x and y

Answer 1

Step-by-step explanation:

In parallelogram the sum of adjacent Angles is 180° so

angle a + angle b= 180°

angle b + angle c=180°

=3x+15+2y+15=180°

=3x +2y+30=180

3x+2y=150........equation 1

=2x+35+2y+15=180°

2×+2y=180-50

2x+2y=130°.........equation 2

by solving equation 1 and 2

3x+2y=150

2x+2y=130

__________

x=20

by substituting x=20 in equation 2 we get

2(20)+2y=130

40+2y=130

2y=130-40

2y=90

y=90/2

y=45

Hence , x=20 y=45

Answer 2

Answer:

x=20,y=45
