Solve the triangle give the measure of y

Given:

In triangle .

To find:

The value of y.

Solution:

In a right angle triangle,

In triangle BGU,

Isolating y, we get

Therefore, the correct option is A.

the formula for the equation of a circle is (x – h)2+ (y – k)2 = r2, where (h, k) represents the coordinates of the center of the circle, and r represents the radius of the circle. if a circle is tangent to the x-axis at (3,0), this means it touches the x-axis at that point.
