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.
If you would like to know the number of minutes of long-distance calls you made, you can calculate this using the following steps:
3.3 cents = $0.033
m = $3.40 / 3.3 cents
m = $3.40 / $0.033 = 3.40 / 0.033
m = 103.03 minutes
The correct result would be <span>103.03 minutes.</span>

Answer: Draw a bisected passing through
Step-by-step explanation:
Answer:
a = p/10 - (3 b)/10
Step-by-step explanation:
Solve for a:
p = 10 a + 3 b
p = 10 a + 3 b is equivalent to 10 a + 3 b = p:
10 a + 3 b = p
Subtract 3 b from both sides:
10 a = p - 3 b
Divide both sides by 10:
Answer: a = p/10 - (3 b)/10
