Answer 2

Answer:

x = 115°

Explanation:

Let angle ABX be y

Given:

angle BAD = 50°

C||D

Construction: produce B to line D on point O

Draw a line from a, bisector of 50° perpendicular to BO at point Z

To find: angle x

Angle AZB = 90°

Angle BAZ = 25°

Angle ABZ = 180° - (90° + 25°)

= 180° - 115° = 65°

Angle ABZ = 65°

In ∆ ABO

x = Angle BAO + Angle ABO

x = 50° + 65°

x = 115°
