The sine ratio is the length of the opposite side expressed over the hypotenuse.

Take the sine inverse of both sides to get;

Answer:
25% of 200 is 50
Step-by-step explanation
40% of a number is 80
.40 * n = 80
Divide each side by .4
.40 n/.4 = 80/.4
n = 200
The number is 200
Now lets find 25 percent of that number
.25 * 200 = 50
First term = T(1) is obtained by plugging n = 1 into the formula,
thus First term = 1^2 - 4 = 1 - 4
= 3 (answer)
Answer:
No, modern train cannot travel on old railroad.
Step-by-step explanation:
In rail transport, track gauge is the spacing of the rails on a railway track and is measured between the inner faces of the load-bearing rails.
Most of the modern train are based on broad gauge. The separation in broad gauge is about 5 ft and 6 inches and in the standard gauge the separation between the tracks is 4 ft and
inches. So for the modern train it is not possible to travel on the tracks whose separation is no more than 4.5 feet.
