Answer:
10.99 m
Step-by-step explanation:
✍️What we are basically asked to solve here is to find the distance between C and D.
To find CD, find the length of BC, and BD. Their difference will give us CD.
Thus, BC - BD = CD.
✍️Finding BC using trigonometric ratio formula:

Opposite side = BC = ??
Adjacent side = 42 m
Thus:

Plug in the values

Multiply both sides by 42


BC = 35.24 m
✍️Finding BD using trigonometric ratio formula:

Opposite side = BD = ??
Adjacent side = 42 m
Thus:

Plug in the values

Multiply both sides by 42


BD = 24.25 m
✍️How much below the top of the tower is the shorter one attached:
Thus,
BC - BD = CD
35.24 m - 24.25 m = 10.99 m
3(x+6)>8-(x-7)
3x+18>8-x+7
2x+18>15
2x>-3
X>-3/2
check the picture below.
so, we know the dimensions of the pool, is a 20x10, so its area is simply 200 ft², and we know the walkway is 216 ft², so the whole thing, including pool and walkway is really 200 + 216 ft².
now, as you see in the picture, the dimensions for the combined area is 20+2x and 10+2x, since the walkway is "x" long, therefore,

notice, it cannot be -18, since is a positive length unit.
Answer:
78%
Convert fraction (ratio) 39 / 50 Answer: 78%
2+x=2x-15
>> 2+15=2x-x
>> 17 = x
So the answer is <u>17</u>
