Question

Q 24 B. In the figure, if / || m, find the value of x.​

Answer 1

Answer:

60⁰ + angle 1 = 180⁰ (both are co interior angles)

angle 1 = 180⁰- 60⁰

angle 1 = 120⁰

angle 1 = angle 2 (vertically opposite)

In ∆ CAB

25⁰ + angle 2 + x = 180⁰ (angle sum property)

25⁰ + 120⁰ + x = 180⁰

145⁰ + x = 180⁰

x = 180⁰ - 145⁰

x = 35⁰
