Question

in triangle
abc if A =90°then angle B + angle C=​

Answer 1

Answer:

90

Step-by-step explanation:

A+B+C=180 (angle sum property of a triangle)

Given A=90°

Putting A= 90 in above equation.

We get

90+B+C=180

B+C=180-90

B+C=90.

Answer 2

Answer:

90

Step-by-step explanation:

always the sum of triangle is 180

there already a=90°

so,180-a=180-90=90

Therefore,a+b=90°

45+45=90
