Question

Ch lines nd angles ques 37

Answer 1

Answer:

37) IF AB || CD

=> a = 55⁰

in triangle ABO, using angle sum property of triangle

A + B + C = 180⁰

55⁰ + B + 60⁰ = 180⁰

115⁰ + B = 180⁰

B = 180⁰-115⁰

B = 65⁰

B = DOC (V.O.A)

DOC = 65⁰

in triangle DOC,using angle sum property of triangle

D + O + C = 180⁰

55⁰ + 65⁰ + C = 180⁰

120⁰+ C = 180⁰

C = 180⁰- 120⁰

C = 60⁰
