Step-by-step explanation:
cot(x) cos(x) + cot(x) = 0
cot(x) (cos(x) + 1) = 0
cot(x) = 0 or cos(x) = -1
cot(x) = 0
x = π/2, 3π/2
x ≠ 0, π
cos(x) = -1
x = π
Therefore, the answer is x = π/2, 3π/2.

Answer:
3:4
Step-by-step explanation:
Before we start to deal with the ratio, we need all lengths in the same units.
The width is 18 inches.
The height is 2 feet.
Let's convert the height to inches. Then we will have both dimensions in the same units, inches.
2 ft * (12 in.)/ft = 24 in.
Now we have:
width = 18 in.
height = 24 in.
ratio of width to height = 18 in. to 24 in. = 18/24 = 3/4 = 3:4
25/5-0.2*5=?
1.(25/5=5)
2.(5-0.2=4.8)
3.(4.8*5=24)
4. the answer is 24
