Question

Which equation can be used to find the measurement of ∠C? To the nearest degree, what is the measurement of ∠A? A) 5sin∠C = 2; 24° B) 29 sin∠C = 2; 68° C) 5sin∠C = 29 ; 22° Eliminate D) 29 sin∠C = 2; 22°

Answer 1

Answer:

Option B

$\sqrt{29}sin(C)=2$  

$A=68\°$

Step-by-step explanation:

see the attached figure to better understand the problem

Part A) Which equation can be used to find the measurement of ∠C?

we know that

In the right triangle ABC

$sin(C)=\frac{2}{\sqrt{29}}$

therefore

$\sqrt{29}sin(C)=2$  

Part B) What is the measurement of ∠A?

In the right triangle ABC

$tan(A)=\frac{5}{2}$

$A=arctan(\frac{5}{2})=68\°$

Answer 2

First guy is incorrect.Answer is actually B
