Answer:
m<4 = 123
Step-by-step explanation:
find thing you need to understand is what is supplementary angles.
if the sum of two angles is 180 degree than it is said to be supplementary.
so
m<3 + m<4 =180
57 + m<4 = 180
m<4 = 180 - 57
m<4 = 123
This is a sohcahtoa question, in this case itd be cosine. The "cah" part stands for cos(x)=adjacent/hypotenuse. Using numbers it would be cos(x)=4/12. To find x youd have to take the cos^-1 of both sides so x=cos^-1(4/12)
