Answer 2

Step-by-step explanation:

we know that 5x-80 and 2x+10 are vertically opposite angles.

therefore,

5x-80 = 2x+10

5x-2x = 10+80

3x = 90

x = 90/3

x = 30.

put x = 30 in 5x-80

5(30)-80

70.

therefore, both the angles are 70.

y + 70 = 90 (linear pair))

y = 20

y = z (vertically opposite angles)

therefore y = 20 and z = 20.
