Answer:
105° is the measurement of the original angle.
Step-by-step explanation:
Let the measure of an angle is x.
Then by the statement of the question we can form an equation
x - 15 = 90
(When 15 is subtracted form the measure of an angle, the result is the measure of a right angle)
x = 90 + 15 = 105°
Therefore the original angle is 105°.
