Find the measure of the exterior angle, x.

Question

1. 52°, 2. 78°, 3. x
x = [?]°

Answer 1

In a triangle, the measure of an exterior angle is equal to the sum of the measures of the two remote interior angles. In your case, we have two angles: 52° and 78°.

To find the exterior angle \( x \), we can use the equation:

\[ x = 52° + 78° \]

Now, we calculate:

\[ x = 52 + 78 = 130° \]

Therefore, the measure of the exterior angle \( x \) is:

\[ x = 130° \]
