Question

Pls help me with the question :)

Answer 1

Step-by-step explanation:

(5x-20) and (3x+8) will be equal since they are Vertically Opposite Angles

5x - 20 = 3x + 8

5x - 3x = 8 + 20

2x = 28

x = 28/2 = 14

now, (5x - 20) and (5x+ 4y) will sum up to 180 degrees because they form a linear pair.

so,

5x - 20 + 5x + 4y = 180 degrees

(5*14) - 20  + (5*14) + 4y = 180

70 - 20 + 70 + 4y = 180

140 - 20 + 4y = 180

120 + 4y = 180

4y = 180 - 120

4y = 60

y = 60/4

y = 15

the value of x=14 and value of y=15
