Question

If triangle abc ab= ac and b= 50 find a

Answer 1

Answer:

a = 80

given ,

ab = ac

b=50

solution

ab = ac means. its an isosceles triangle

and base angles are same

therefore, b = c = 50

now by sum of measures of angles of triangles

a+b+c=180

a + 50 + 50 =180

a+ 100= 180

a= 180 - 100

a=80
