Question

please give all the steps.
please answer fast

Answer 1

5a=2a+60°(vertically opposite angle)
5a-2a=60°
3a=60°
a=60°/3
a=20°..

Verification
5a=5×20=100°
2a+60°=2×20°+60°=100°
Hence 100°=100°=

Now
angle b = angle O=x (vertically opposite angle )
100+100+x+x=360°
200°+2x=360°
2x=360°-200°
x=160°/2
x=80°=angle b=angle o
I hope it will help uh.

Answer 2

Vertically opposite angles are equal

Since vertically opposite angles are equal: 5a = 2a + 60°

Bringing all the 'a' terms to one side (and sign changes accordingly) : 5a - 2a = 60°

3a = 60°

a = 60°/3

a = 20°

Therefore the two angles are 5a = 5*20 = 100° and 2a + 60° = 2*20 + 60° = 100°

Hope it helps :)
