Question

B) in a ∆abc, ab = ac and ∠a = 500 find ∠b and ∠c

Answer 1

Answer:

the angle is 50 degrees and not 500,

Because in a triangle the sum of all the triangle should be 180degree

Not first draw the triangle,as the two sides are eaual the angle opposite to them Would also be equal……………..isosceles angle theorem consider the angle as x

So,

50+x+x=180

2x=130

X=65

Angle B and C measure 65degrees
