Question

3 In ALMN, ZN is a right angle, LM = 76 units, and MN = 40 units. What is the approximate measure of ZM? OA 58° OB. 28° O C. 32° OD. 40°

Answer 1

The answer will be C. 32 degrees because use the identity of the function sinus we have that

`\sin (x)=(40)/(76)\Rightarrow\sin (x)=(10)/(19)\Rightarrow x=\sin ^(-1)((10)/(19))\approx32`
