Answer:
15 units
Step-by-step explanation:
The picture of the question in the attached figure
we know that
Triangle XYZ is a right triangle, because segment ZY is tangent to circle X at point Y
so
Applying the Pythagorean Theorem

we have

substitute the given values


5x-10=2x+5
We simplify the equation to the form, which is simple to understand
5x-10=2x+5
We move all terms containing x to the left and all other terms to the right.
+5x-2x=+5+10
We simplify left and right side of the equation.
+3x=+15
We divide both sides of the equation by 3 to get x.
x=5

First, find the length of the hypotenuse using the Pythagorean theorem: a^2+b^2=c^2
25 + 144 = c^2
= c^2
13 = c
Now, find each of the values! Sin = opposite/hypotenuse; Cos = Adjacent/hypotenuse; Tan = Opposite/Adjacent.
