Finding an angle measure given extended triangles
Find $x$.
\[
x=
\]
Solution
Solution Steps
Step 1: Identify the given angles
The problem provides two angles: 56° and 102°.
Step 2: Recognize the relationship between angles
The angles 56° and 102° are exterior angles of the triangle. The sum of the interior angles of a triangle is always 180°.
Step 3: Calculate the unknown angle
To find the unknown angle \( x \), we use the fact that the sum of the interior angles of a triangle is 180°. The unknown angle \( x \) is the exterior angle opposite to the interior angle 56°.
Since the exterior angle is equal to the sum of the two non-adjacent interior angles, we have:
\[ x = 56° + 102° \]
