A side of the triangle below has been extended to form an exterior angle of 142°. Find the value of xx. 142° x°
To find the value of x, we need to use the fact that the sum of the interior angles of a triangle is always 180 degrees.
The exterior angle is equal to the sum of the two remote interior angles. In this case, the exterior angle is given as 142 degrees, so we can write the equation:
x + 142 = 180
Solving for x, we get:
x = 180 - 142
x = 38
Therefore, the value of x is 38 degrees.
