Answer:
C
Step-by-step explanation:
The degrees of a triangle add up to 180.
Angle C is already 90 degrees therefore angle A + angle B = 90 degrees.
Angle A is equal to sinA=1/2.
sinA=1/2 is equal to 30 degrees if you press 2nd, sin (1/2) into the calculator. You may also know this if you have memorized the values of trig.
90-30=60.
That leaves you with 60 degrees for angle B.
