The calculated measure of the third angle is 69 degrees
How to determine the measure of the third angle
The sum of the interior angles in a triangle is always 180 degrees.
To find the measure of the third angle in a triangle when two angles are known, you can subtract the sum of the given angles from 180.
Let's represent the three angles in the triangle as A,B, and C.
We are given that one angle measures 63 degrees
A = 63∘
And another angle measures 48 degrees
B = 48∘
To calculate C, we have
C = 180 − (A + B)
Substitute the given values:
C = 180 − (63 + 48)
Evaluate
C = 69
Hence, the measure of the missing angle is 69 degrees
