Ineed with this pre calc worksheet, due tomorrow!
can someone me answer these problems and explain the process, ?
i really don’t get it

1011.05

Step-by-step explanation:

Let's use 3 as an example.

The angle of depression is the one directly under the ballon.

You also know that the 53 degree angle is part of a 90 degree angle.

so the angle inside the triangle directly under the balloon is 37 degrees.

You know the angle and you know the side from the balloon to the ground is 1680.  This is the hypotenuse of the triangle.

So which trig function could you use to determine how high the balloon is from the ground?

SOH CAH TOA

cos 37 = a/1680

a = 1341.71

-3

step-by-step explanation:

a drawing really does here:

so i draw the horizontal line y=2 and the vertical line x=-2 at this intersection i put b (this is where my right angle is going to be).   so point b is at (-2,2).   point a is 5 units long and is also on y=2 so this point has to be (3,2) or (-7,2) -doesn't matter i will go with (3,2).

now we know c is at (-2,y) we don't know the y yet bet we know that c is on x=-2.

we have the area of the triangle is .5bh=12.5

we know the base length is 5 (ab)

we have the height is (2-y) if you look at your

plug in

.5(5)(2-y)=12.5

solve for y to get the y-coordinate for c

2.5(2-y)=12.5

divide both sides by 2.5 giving:

2-y=5

now subtract 2 on both sides

-y=3

y=-3

step-by-step explanation:

to find if any function is an inverse of the other, put the first equation in as x in the next one. then simplify and solve. if at the end you get the statement y = x, then it is an inverse. if you get anything else, it is not.
