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.

Answer 1

C=45 degrees

Step-by-step 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.
