In triangle ABC, the measure of angle B is 27 degrees more than three times the measure of angle A.
The measure of angle C is 48 degrees more than the measure of angle A.
The measures of the three angles in a triangle must total 180 degrees.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 

B = 3A + 27 degrees.

C = A + 48 degrees.


A + B + C = 180,   or, substituting,

A + (3A+27) + (A+48) = 180  --->

5A + 75 = 180  --->  5A = 180 - 75  --->  5A = 105  --->  A =  = 21 degrees.

Having A, can you find B and C on your own and to complete the assignment ?
