Answer:
Step-by-step explanation:
Tan can be defined as: 
as it simplifies to opposite/adjacent. If you know a bit about the unit circle, you'll know that the x-coordinate is going to be cos(theta) and the y-coordinate is going to be sin(theta). Since the sin(theta) is defined as opposite/hypotenuse, and the hypotenuse = 1, so sin(theta) is defined as the opposite side, which is the y-axis. Same thing goes for cos(theta), except the adjacent side is the x-axis.
Using this we can define tan
The answer is D because 42 / 6 = 7 and the power ( ^X) can cancel out each other
Setup: 4x-6=3x+4
<span>4x=3x+10 </span>
<span>1x=10 </span>
x = 10
