Question

15. ABC is a right angled triangle in which angle A = 90° and AB = AC, find angle B and angle c
​

Answer 1

Answer:

B = 45°

C = 45°

Step-by-step explanation:

Answer 2

Step-by-step explanation:

A triangle interior angal was 180 degree

so,

A+B+C= 180°

A=90° and

we know angle BC^2= AB ^2 + BC^2

we know that,

90°+B+C = 180

B+C= 180-90

B+C=90°

we know b=c

so when we let angle b=x so angle c=x

x+x =90

2x=90

x= 90/2

x= 45

we know b=c b=45

and c= 45
