Because I just got in wrong.
Answer look on quziz and quizlet they give answers hope that helps
Step-by-step explanation:
Answer:
107°
Step-by-step explanation:
m∠m+m∠p= 180°
(7x+31)°(21x-19)°=180°
7x+31+21x-19= 180
7x+21x=180+19-31
28x=168
x= 168/28
x= 6
m∠p= (21x-19)°
= (21(16)-19)°=(126-19)°
= 107°

have a great day!!
Adjacent, cosine again.
a = c cos B = 13 cos(16+45/60) = 13 cos(16.75) = 12.448
Choice a
