Answer (simplified ): 1:2
8 + 2 = 10/20
In ratio form that is 10:20
10:20 *simplified by 5* = 5:10
5:10 *simplified by 5* = 1:2
Or you can simplify 10:20 by 10 and then just get 1:2 as your ratio answer

Answer:
cot θ = √15 / 7
Explanation:
csc θ = 1 / sin θ
In a right angled triangle, sin θ = opposite / hypotenuse
This means that:
csc θ = hypotenuse / opposite = 8 / 7
So, we have:
opposite = 7 units and hypotenuse = 8 units
We will use the Pythagorean theorem to get the adjacent side as follows:
(hypotenuse)^2 = (opposite)^2 + (adjacent)^2
(8)^2 = (7)^2 + (adjacent)^2
(adjacent)^2 = 15
adjacent = √15 units
Now, we want to get the value of cot θ.
We know that:
cot θ = 1 / tan θ
Since tan θ = opposite / adjacent
Therefore:
cot θ = adjacent / opposite = √15 / 7
Hope this helps :)
Answer:
Step-by-step explanation:
Well you only want the two equations so here they are.
x + y = -7
5*x + y = 1
I should give you the answer.
x = 2
y = -9 I think. These answers were done in my head.
Answer:
speed = (125×1000/2×60×60) m/s
=125000/7200 m/s
=17.36 m/s
