If the plane climbs at 12° from the ground, it is (90 - 12 = 78)° from the perpendicular line. 

Let the horizontal distance be x.

sin(78) = x/500
x = 500 sin (78)
x = 487.07 feet

-------------------------------------------------------------------------------------
Answer: The horizontal distance is 487.07 feet.

What is the equation of the line whose y-intercept is 3 and slope is 1? A.y = x + 3 B.y = 3x + 1 C.y = x - 3
mario62 [17]

Answer:

The answer is option A

Step-by-step explanation:

Equation of a line is y = mx + b

where

m is the slope

b is the y intercept

From the question

b / y intercept = 3

m / slope = 1

Substitute these values into the below equation

y = mx + b

We have the answer as

y = x + 3

Hope this helps you

What basic trigonometric identity would you use to verify that sin x +1/ sin x=1 +csc x
SVETLANKA909090 [29]

Answer:  The correct option is (c). \csc x=\dfrac{1}{\sin x}.

Step-by-step explanation:  We are given to select the correct basic identity that we will use to verify the following:

\dfrac{\sin x+1}{\sin x}=1+\csc x.

We have

\dfrac{1+\sin x}{\sin x}\\\\\\=\dfrac{1}{\sin x}+\dfrac{\sin x}{\sin x}\\\\\\=1+\dfrac{1}{\sin x}.

In order to verify the given trigonometric equation, we must have

1+\dfrac{1}{\sin x}=1+\csc x\\\\\\\Rightarrow \dfrac{1}{\sin x}=\csc x\\\\\\\Rightarrow \csc x=\dfrac{1}{\sin x}.

Thus, the required identity that we will use is

\csc x=\dfrac{1}{\sin x}.

Option (c) is CORRECT.
