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