Question

X=
The measure of the exterior angle of the triangle is:
​

Answer 1

x= 52

exterior =102

Explanation:

50+x=3x-54

50+54=3x-×

104=2x

52=x

3(52)-54

156-54=102

Answer 2

Explanation:

We know that

`\sf \hookrightarrow \: \boxed{ \sf \: sum \: of \: two \: interior \: angles = exterior \: angle} \\ \sf \hookrightarrow \: 50 + x = 3x - 54 \\ \sf \hookrightarrow \: x - 3x = - 54 - 50 \\ \sf \hookrightarrow \: - 2x = - 104 \\ \sf \hookrightarrow \: 2x = 104 \\ \sf \hookrightarrow \: x = (104)/(2) \\ \sf \hookrightarrow \: x = 52`
