Question

sum of two vertically opposite angels is 156° find each of us angle

Answer 1

sum of vertically opposite Angles is 156 °
So let's suppose each of its angle to be X
so X+X =156°
2x=156
so X=156/2=78°
So each of this angle is 78°
Hope it is helpful...

Answer 2

sum of two vertically opposite angles is 156°____(given)
Let us consider two vertically opposite angles be /_A and /_ B respectively.
vertically opposite angles are always congruent.
Therefore, /_ A = /_ B = x°
Sum of both vertically opposite angles is 156°
》/_A+/_B=156°
》x°+x°=156°
》2x°=156°
》x°=156°/2
》x°=78°
Hence, /_A=/_B=78°
ANS: The measure of each angle is 78°.
