If a triangle has two angles that measure 45 and 90 degrees, what is the measure of the third angle
A. 90
B. 60
C. 45
D. 30

Answer:
45°
Step-by-step explanation:
if you add up all interior degrees in a triangle you'll get 180° so if two of the given angle is 90 and 45 then the third one must be 45 to complete the rule.
