Answer:
d. 30x ≥ 180
Step-by-step explanation:
if x is the number of lawns and 30 is how much he gets for each lawn, it would be 30x. And in this situation, it needs to be equal to or more than 180.
Tan0 = opposite/adjacent
To find the opposite side you need to use Pythagoras Theorem.
Where
a^2 + b^2 = c^2
Rearrange for b^2 term
c^2 - a^2 = b^2
c=8 a=7
64-49 = 15
B is equal to square root 15 which is equal to length of opposite side.
Since Tan0 = opposite/adjacent
= root 15/7 is the answer
