Answer:
2644.415 feet spuared
Step-by-step explanation:
I think the attached photo is your full question, and my answer:
We need to find:
- the area of the pool = π = 3.14* = 1319.585 feet spuared.
- The area of the triangular fence = 1/2* 84*92 = 3964 feet spuared
So, the area of the backyard which is not covered by the pool is:
The area of the triangular fence - the area of the pool
= 3964 - 1319.585
= 2644.415
Hope it will find you well.
Answer:
35/37
Step-by-step explanation:
In this question, we are to calculate the ratio that represents the cosine of angle O
Firstly, please check attachment for diagram of the triangle.
Mathematically, the trigonometric term Cos means the ratio of the length of the adjacent to that of the hypotenuse
The hypotenuse is the longest length which is 37 which represents the length ON
The side adjacent to angle O is the side OP which is 35
Thus, the ratio representing the cosine of angle O is 35/37
