Question

A triangle contains angles mesuring 28 degrees and 37 degrees. How many degrees is the third angle?​

Answer 1

• 115°

Explanation:

We know that:

• Angles ∠A and ∠B are 28° and 37°.

We don't know:

• Angle ∠C's angle

So, we do this:

• Add the 180°
• Solve the equation 180 - 28 - 37

Solve:

• 180 - 28
• = 152 - 37
• = 115.

Angle ∠C is 115°.
