By the interior angles theorem, if angle a is 25 degrees and angle b is greater than 51 degrees but less than 57 degrees what are the possible measurements for angle c

By interior angles theorem, that the sum of the interior angles of a triangle is 180 degrees. So the possible angle C can be calculated by the formula

180 = a + b + c

(180 - 25 - 57) < c < (180 - 25 - 51)

98 < c < 104 is the possible measure of angle c
