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
Step-by-step explanation:
B is the correct answer. you can not multiply the first ratio be anything to make it equal the 2nd.
If you have a question to ask, then what is it ?
I notice that IF AB and DE are parallel, then the two triangles tip to tip at C are similar. That may help you.
The resulting equation if Becca isolated x² in the first equation and then substituted it into the second equation is (9-y²) / 25 - y²/36 = 1
<h3>Equation</h3>
x² + y² = 9
x²/25 - y²/36 = 1
From (1)
x² = 9 - y²
substitute x² = 9 - y² into (2)
x²/25 - y²/36 = 1
(9-y²) / 25 - y²/36 = 1
Therefore, the resulting equation is option C; (9-y²) / 25 - y²/36 = 1
