Question

5. In the given figure, pllq and rlls. Find the angles a, b and c.​

Answer 1

Step-by-step explanation:

angle a = 80° [ Vertically opposite angle (VOA)]

angle c = (180-80)°= 100° [ alternate and VOA]

angle b = angle c = 100° [ corresponding angles]

Hope this helps...

Answer 2

Answer and Explanation:

∠A:-

80° =  ∠A [vertically opposite angles]

Therefore, ∠A = 80°.

∠C:-

∠C + 80° = 180° [exterior allied angles]

∠C = 180° - 80°

∠C = 100°

Therefore, ∠C = 100°

∠B:-

∠B = Angle C [corresponding angles]

∠B = 100°

Therefore, ∠B = 100°
