Question

ABC is a right angled triangle in which A= 90° and AB = AC find B and C​

Answer 1

Step-by-step explanation:

by by Pythagoras theorem we will find b and c

Answer 2

Step-by-step explanation:

GIVEN : ABC is a right angled triangle

A = 90°

AB = AC

TO FIND : angleB and angleC

SOLUTION : angleC = angle B (angle opposite to

equal sides are also equal)

Let angleB = angleC = x

In ∆ABC,

angle A + angleB + angleC + 180° (angle sum

property of a ∆)

90° + x + x = 180°

90° + 2x = 180°

2x = 180° - 90°

2x = 90°

x = 90/2

x = 45°

therefore, angleB = angleC = 45°
