x =
°
triangle a b c. the measure of angle a is fifty five degrees, the measure of angle b is eighty degrees and the measure of angle c is x.

C=45 degrees

Explanation:

Important thing to know about triangles is that the sum of its angles is always 180 degrees, so whether it is equilateral, isosceles, scalene or right triangle they`re angles always sum up to 180 degrees. We can express that by an equation: A + B+ C = 180 degrees. So, in this case we have 55 + 80 + C = 180 degrees.  Now we can calculate the value of the angle C.

C= 180-(55+80)

C= 180 - 135

C= 45 degrees

So the x, or in this case the angle C is 45 degrees.
