find the measure of each angle.
c ,
mza =
mzb =
mzc =

°

°

°

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, °.
