Find The Measure Of Each Indicated Angle To The Nearest Degree A30 B56 C50 D34 class=

Answer :

Step 1

Name the sides of the triangle.

Hypotenuse = 6, the side facing right angle

Opposite = ? side facing given angle

Adjacent = 5

Step 2

Apply the cosine angle formula to find the indicated angle.

[tex]\begin{gathered} Cos\theta\text{ = }\frac{adjacent}{\text{Hypotenuse}} \\ \cos \theta\text{ = }\frac{5}{6} \\ \cos \theta\text{ = 0.8333333333333333333333} \\ \theta\text{ = }\cos ^{-1}0.8333333333333333 \\ \theta=\text{ }33.55 \\ \theta=\text{ 34} \end{gathered}[/tex]

The measure of the indicated angle = 34
