Answer: C
Step-by-step explanation:
To get all the constant terms on one side and variable terms on another, all we have to do is to add or subtract them on both sides.
3x+2x=10+5
Now that the like terms are on one side, we can combine them.
5x=15
To get x alone, we divide both sides by 5.
x=3
Now, we notice that x=3 is not an answer choice, but the next option that is equivalent to x=3 is C.
For C, if you divide both sides by -5, you still get x=3.
-15=-5x
x=3
So you know that the triangle is a right triangle, and that means that the work is pretty straightforward:
You 'know' the measure of angle x and one of the legs of the triangle, so when trying to find the distance of the second leg of the triangle, use the Tangent function because the tangent of angle x = opposite leg / adjacent leg.
Since we know the measure of the adjacent leg and the angle measure, solve for the opposite leg's measure:
tanx = opposite / y
opposite = y * tanx
This means that the distance between the Earth and the Moon is equal to the tangent of the angle of the sun's rays between the Earth and Moon times the distance between the Sun and Earth.
