Find the value of x .

x=81

Step-by-step explanation:

This is a triangle,to solve you have to be calm and reason well

We are given two angles in the question and normally a triangle should have three angles

It was discovered that one of this angle is not placed inside the triangle so we will have to look for a way to bring it in...to do that, let's represent the inner part to be t

139+t=180(angle on a straight line)

t=180-139

t=41

Therefore the angle inside the triangle is 41

Sum of the triangle is 180

58+x+41=180

Collect like terms

58+41+x=180

99+x=180

Substrate 99 from both sides

x=81

Therefore x is 81
