Question

Two angles measures x -50 and 121 – 2x. If each one is opposite to equal sides of an isosceles triangle, then find the value of x.

Answer 1

Answer:

57

Step-by-step explanation:

the equation will be

x-50 = 121 - 2x

3x = 121 + 50

3x = 171

x= 171/3

x = 57

Answer 2

Answer:

x =57 degree

Step-by-step explanation:

opposite angles of isosceles triangle are equal .

so

121-2x =x-50

171=3x

x=57
