A triangle has two angle measures of 82° and 55°. What is the measure of the missing angle?

Answer 1

To find the measure of the missing angle in the triangle, we need to first calculate the sum of the three angles.

So, the sum of the three angles in a triangle is always 180°.

Given that two angle measures are 82° and 55°, we can add them together to find:

82° + 55° = 137°

Now, to find the missing angle, we subtract the sum of the two known angles from 180°:

180° - 137° = 43°

Therefore, the missing angle in the triangle is 43°.
