Question

1 Tng Ratlos POSSIBLE 12 21 ? 24 in the above triangle, would you use SINE, COSINE, or TANGENT to solve for the missing side (TYPE IN ALL CAPS)? (ROUND TO THE NEAREST DEGREE) The measure of the missing angle is 1 2 3 4 5 6 7 K A O

Answer 1

According to the given values, we should use the COSINE ratio to find the missing side. This once we have found the missing angle.

To do it we can use sine ratio and the given values of the opposite side and the hypotenuse:

$\begin{gathered} \sin x=\frac{12}{24} \\ \sin x=0.5 \\ x=\sin ^{-1}0.5^{} \\ x=30 \end{gathered}$

The missing angle measures 30°.
