Answer 1

N = 2.1

M = 4.5

Explanation:

<p is 25 degrees. I know this because the exterior angle of p corresponds with 155. Since this is a straight angle, angle p must be 25 (180-155). Now I can use the cos and the sin of 25 to find M and N

sin 25 = N/5 multiply both sides by 5 to get

5 sin 25 = N Use your calculator put in 5 sin 25

2.1 rounded to the nearest tenth.

cos 25 = M/5 Multiply both sides by

5 cos 25 = M Use your calculator

4.5
