Question

in isosceles right triangle ABC if angle A=90° find value angle B and angle C​

Answer 1

Answer:

B=45degree

C=45degree

Step-by-step explanation:

in an isosceles triangle the angles opposite to equal sides are equal

therefore,

A+B+C=180degree

90+x+x=180

2x=90

x=45degrees

Answer 2

Let angle B and angle C be x° and ° .

We know that sum of all angles of Triangle is 180°.

Angle A + Angle B + Angle C = 180°

90 + x + x = 180

2x = 180 - 90

2x = 90

x = 90/2

x = 45

Therefore, Angle B = x° = 45°

Angle C = x° = 45°
