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
Y=3x-14 or 3x-14=Y
This is because you want to keep y positive, and so you add Y on both sides and get 3x=14+y, then you want to get y alone so you subtract 14 on both sides and get 3x-14=Y

A right triangle contains a right angle, so it must have two sides that are perpendicular. If the slopes of two sides can be shown to be negative reciprocals of each other, then it can be concluded that a right angle is formed. If a triangle contains a right angle, then it is a right triangle.
