Step-by-step explanation:
Let the measure of angle C be
°.
Given:
In triangle ΔABC,
is thirteen less than
and
is eleven less than four times
. This gives,


Also, 
Now, for a triangle, the sum of all its interior angles is equal to 180°.
Therefore, 
Plug in all the values and solve for x. This gives,

Therefore, measure of angle C is 34°.
Measure of angle A is,
°.
Measure of angle B is,
°.
