Answer:
c) 12/15 = 4/5
Step-by-step explanation:
imagine we mirror the triangle up, so that Z is on top.
then you can clearly see that 6 is cos(X) times r (and r is then 7.5).
XY is sin(X)×7.5
and again, 7.5 is r (the line making the X angle).
so, the cosine ratio of X is
6 = cos(X)×7.5
cos(X) = 6/7.5 or then 12/15. or simplified 4/5.
Answer:
3y^2 3√3y(end route) if you are simplifying, and (81y^7)^1/3 if you are rewriting it.
Step-by-step:
I know this!
75°+75°=150°
angles in a triangle add up to 180°
180°-150°=30°
c) x=30°
