Answer:
angle c = 107°
angle b = 107°
angle a = 73°
Step-by-step explanation:
Given:
Two line XY and WZ intersect each other and make four angle [a, b, c, d]
Given that Angle d = 73°
Find:
angle a
angle b
angle c
Computation:
We know that angle c and angle d situated on same line XY
So,
angle c + angle d = 180°
angle c + 73° = 180°
angle c = 107°
We know that angle b and angle d situated on same line WZ
So,
angle b + angle d = 180°
angle b + 73° = 180°
angle b = 107°
angle a and angle d are vertical opposite angle
So,
angle a = angle d
angle a = 73°
