Question

in given figure line AB bisects angle COD. If angle BOC = 65° find the measure of angle AOD and angle AOC​

Answer 1

Answer:

Given that X = 45°

Find: the value of Y, Z, and u

z = x = 45° [Vertically opposite angles are equal]

z + u = 180° [z and u are angles that are a linear pair]

z = 180° – u

u = 180° – x

u = 180° – 45°

u = 135°

x + y = 180° [x and y angles are a linear pair]

y = 180° – x

y =180° – 45°

y = 135°

Hence, x = 45°, y = 135°, z = 135° and u = 45°
