Question

9. In a right angled triangle where angle A= 90° and AB-AC. What are the values of
angle B.​

Answer 1

Answer:

Solved⤵️

Step-by-step explanation:

Therefore; In triangle ABC

AB= AC

Therefore; Angle B = Angle C

| Angles opposite to equal sides of a triangle were equal

In triangle ABC,

| Sum of all angles of a triangle is 180°

=> 90° + Angle B +Angle C = 180°

|Therefore; Angle A is 90° ( given )

=> Angle B +Angle C = 90°...(2)

From (1) and (2) , we get

Angle B = 45°
