Question

In angle ABC, if angle A = angle B + angle C
then angle A =
​

Answer 1

Answer:

if its isosceles then 45 + 45 = 90

or angle b + angle c = angle = angle a

Step-by-step explanation:

Answer 2

Answer:

as the sum of three angles of a triangle is 180°

now let, the sum of angle B and angle C be 2x

so angle A=2x

so, 2x+2x=180°

=4x=180°

=x=45°

hence the value of angle A=45×290°
