Recall that tanA = sinA / cosA.
Therefore, tanA = (3/5) / (4/5) = 3/4.

Answer:
y = 2
Step-by-step explanation:
use slope formula:
(4 - y) / (3 - 10) = -2/7
4-y / -7 = -2 /7
cross-multiply:
7(4 - y) = (-7)(-2)
28 - 7y = 14
-7y = -14
y = 2
Together they mowed 1565 11/50 square yards. You have to make the fractions have same denominators so you can add, after fixing the denominators, just add.
Answer: 40 cones
Explanation: If the blue cones (of which there are 10) are 25% or one quarter of the total number of cones, that means that the total number is equal to four times that, or 40.
10 = 25%
total = 100%
25% x 4 = 100%
10 x 4 = 40
