The calculated measure of the angle T is 102 degrees
How to determine the measure of the angle T
From the question, we have the following parameters that can be used in our computation:
The triangle
Where, we have
R = 18 degrees
S = 60 degrees
The sum of angles in a triangle is 180 degrees
So, we have
T = 180 - R - S
Substitute the known values into the equation
T = 180 - 60 - 18
Evaluate
T = 102 degrees
Hence, the measure of the angle T is 102 degrees
