Answer:
75°
Step-by-step explanation:
Since the 2 angles are supplementary and TC is a perpendicular bisector, we know that m∠ATC is 90°
All we need to do is simply subtract 15° from 90° to find m∠ATB:
90 - 15 = 75°
Answer:
570
Step-by-step explanation:
Y=f(x) between x=a and x=b, integrate y=f(x) between the limits of a and b
C. because 3/6 is equal to 1/2.
c is 1/2 of 1
one thing to be noteworthy is that this triangle has two angles, a 60° one and a 90° one, meaning the last angle will be a 30° one, thus we can use the 30-60-90 rule.
