Question

Find the measure of the indicated angle to the nearest degree. HELP PLEASE WILL GIVE POINTS AND BRAINLIEST

Answer 1

Answer:

1. 73 degrees   2.  53 degrees

Step-by-step explanation:

1.  In this triangle, the opposite side has length 22, the hypotenuse has length 23.  The trigonometric ratio that uses opposite and hypotenuse is the sine.

The sine = (opposite) / (hypotenuse) so the sine of the angle is 22/23.

Use the inverse sine function to find the angle.

$\sin^{-1} (22/23) \approx 73^\circ$

2.  In this triangle, the adjacent side has length 3, the hypotenuse has length 5.  The cosine ratio uses these two sides.

The cosine = (adjacent) / (hypotenuse) so the cosine of the angle is 3/5.

Use the inverse cosine function to find the angle.

$\cos^{-1}(3/5) \approx 53^\circ$

Im pretty sure it’s 1 don’t be mad if it’s not pls
