Question

A triangle is isosceles. if one angle of the triangle measures 102°, what are the measures of the largest and smallest angles of the triangle?

Answer 1

  the sum of three angles = 180 

a + b +c = 180 

a=102   and b= c (triangle is isosceles)

so  b+c= 180- 102
b+c=  78

b= c= 78 /  2 =  39
