Answer:
180-115=65
Step-by-step explanation:
What makes it a acute angle is because it’s less than 90 degrees
And u subtract 180 from 115 because a line equals 180 and one side is 115 so to find the angle of the other side u subtract it from 180 now if the angle is less than 90 it’s acute and if it’s greater it’s obtuse angle and if 90 it’s a right angle
