In a right triangle, relative to one of the acute angles ( $\theta$ ), the adjacent side measures 25 m and the hypotenuse measures 43 m. What is the measure of angle  $\theta$  to the nearest whole degree?

•  $30\degree$  

•  $54\degree$  

•  $36\degree$  

•  $60\degree$  

Using the given diagram, determine the measure of the hypotenuse to the nearest whole number. (DO NOT include degrees/words in your response. Just the number.)

Determine the value of: sin(C)

• 7 / 25
