The points A and B and the center O of the circle form a right angle and AO = radius.
So by Pythagoras
16^2 = 15^2 + AO^2
AO = sqrt (16^2 - 15^2)
AO ( radius) = sqrt31 = 5,57 feet answer (to nearest hundredth)
Answer:
B. 10
Step-by-step explanation:
These are vertical angles meaning they are also equal.
<span>If c = 30 and d = 8, then
2c + 4d
= 2(30) + 4(8)
= 60 + 32
= 92</span>
