Question

how to find the missing angle?​

Answer 1

Step-by-step explanation:

Missing Angles in Triangles Knowing that a triangle contains 180° makes calculating the measure of a missing angle much simpler.

Let's take a look at some examples.

Example #1:

Determine the measure of angle x.

Step 1: Add together the known angles.

68° + 47° = 115°

Step 2: Subtract the sum from 180°.

180° - 115° = 65°

The measure of angle x is 65°.
