Pls help! <br> Find the value of the variable.
Oksi-84 [34.3K]

Answer:

Step-by-step explanation:

A tiny hint. When you are looking for the opposite side of a triangle and the function you use is the tangent, the side opposite is always going to be larger than the side adjacent. That happens when theta is greater than 1 when the angle is larger than 45.

Phew!  I didn't know the hint was going to be that long.

The trig function that does not involve the hypotenuse is the Tangent or Tan(x).

C

Tan(x) = opposite / Adjacent.

The opposite side is the side not connected to the reference angle (x)

The adjacent side makes up the angle and is not the hypotenuse.

Tan(46) = 1.036

Side adjacent = 8

So the answer is either A or C. I'm guessing it's C.

Tan(46) = x/8

1.036 = x / 8                   Multiply by 8

8*1.036  = x

x = 8.28
