Answer 1

x = 130 degrees

Explanation:

Here, we want to find the value of x

mathematically, the sum of opposite interior angles equal the opposite exterior angles

In the triangle, we have only one interior angle

Now, as we can see, the angle that measures 150 is on a straight line with one of the angles in the triangle

Mathematically, the sum of angles on a straight line is 180

So we have it that the given angle in the triangle would be (180-150)

If we add this to the 100, we have the exterior angle which is x

Thus, we have it that;

x = 100 + (180-150)

x = 100 + 30

x = 130 degrees
