Find sin A. 12/13<br> B. 1<br> C. 13/12<br> D. 13/5

vladimir1956 [14]

Answer: A. $\frac{12}{13}$

Step-by-step explanation:

The best way to remember this is SOH-CAH-TOA. For sin, it would be the opposite angle over the hypotenuse. The opposite angle of ∠C is 24 and the hypotenuse is 26. But that isn't in the answer choices, so you'll simplify the fraction.

$\frac{24}{26} =\frac{12}{13}$ , therefore, the answer is A.

I hope this helps! Pls mark brainliest!! :)

How to find the height of a cylinder knowing the volume

Minchanka [31]

Hello!

The formula for volume of a cylinder is:

V = pi × r^2 × h

You'll do the opposite to find the height:

H = V ÷ pi × r^2

As you can see, you need the volume and the radius to find the height.
