Question

Which of the following equations could be solved to determine the length of RS?

Answer 1

Answer:

$\frac{Sin(80)}{RS} = \frac{Sin(52.5)}{7}$

Step-by-step explanation:

Given:

S = 52.5°

s = QR = 7

Q = 80°

q = RS = ?

Required:

Equation that could be used to find the length of RS

Solution:

We would need the law of Sines which is given as:

$\frac{Sin(A)}{a} = \frac{Sin(B)}{b} = \frac{Sin(C)}{c}$

Applying the Law of Sines, we would have the following equation:

$\frac{Sin(Q)}{q} = \frac{Sin(S)}{s}$

Plug in the values

$\frac{Sin(80)}{RS} = \frac{Sin(52.5)}{7}$

Therefore, the equation that can be used to determine the length of RS is $\frac{Sin(80)}{RS} = \frac{Sin(52.5)}{7}$
