X=135 you have to distibute the three to the 180 and the -x and you get x=540-3x then you add the -3x to the other x which is called combining like terms now you have 4x=540 then you divide the four on both sides to get the x alone now you have x=135

Answer:

7949.13 feet

Step-by-step explanation:

We are given that,

Angle of depression from the spot to the group = 39°

Height of Grand Canyon = 5000 feet.

So, we will get the following figure of a right triangle.

As, 'in a right triangle, the angles and the sides can be written in trigonometric form'.

We get, $\sin A=\frac{perpendicular}{hypotenuse}$

i.e. $\sin 39=\frac{5000}{x}$

i.e. $x=\frac{5000}{\sin 39}$

i.e. $x=\frac{5000}{0.629}$

i.e. x = 7949.13 feet

Thus, the line of sight distance is 7949.13 feet.

2^x-2

When x=0

We have 2^0-2

1-2=-1

when x=1

We have 2^1-2

2-2=0

When x=2

We have 2^2-2

Answer:

924/5 ft/s
369.6 ft

Step-by-step explanation:

126 mi/h = (126 mi)/(1 h)·(5280 ft)/(1 mi)·(1 h)/(3600 s) = (126·5280/3600) ft/s

126 mi/h = 184.8 ft/s = 924/5 ft/s

In 2 seconds, the parachutist falls ...

(184.8 ft/s)·(2 s) = 369.6 ft
