Question

in an isosceles triangle,the base angles are equal.the vertex angle is 40.whatare the base angles of the triangle?let the number be x.this is a simple equation.the sum is 180

Answer 1

x=x

sum of all interior angle of a triangle=180
so,
40+x+x=180
2x=180-40
x=140÷2
x=70

Answer 2

x=x sum of all interior angle of a triangle so
40+x+x=180
2x=180-40
x=140÷2
x=70
