Step-by-step explanation:
Correct answer:
C=65
Explanation:
First, know that all the angles in a triangle add up to 180 degrees.
Each triangle has 3 angles. Thus, we have the sum of three angles as shown:
180=A+B+C
where we have angles A, B, and C. In our right triangle, one angle is 25 degree and we'll call that angle A. The other known angle is 90 degrees and we'll call this angle B. Thus, we have
180=25+90+C
Simplify and solve for C.
180=115+C
C=65
