r to the 4th power = r⁴
t to the third power = t³
r to the 4th power times t to the third power would be written as:
(r⁴)(t³)
Answer:
The three interior angles of triangle are equal to 180. Since you already have 2 of those angles, you just subtract both of them from 180 to find x. So, 25+30=55, 180-55=125. The measure of angle x is 125.
