Question

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

Answer 1

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!! :)
