we are given the following triangles:

We are asked to determine the value of "y". To do that we will use the tangent of 25:


\tan 25=(y)/(x)

We solve for "y" by multiplying both sides by "x":


x\tan 25=y

Now, we take the tangent of 15:


\tan 15=(y)/(30+x)

Now, we solve for "y" by multiplying both sides by the denominator:


(30+x)\tan 15=y

Now, we set both values of "y" equal, we get:


x\tan 25=(30+x)\tan 15

now, we solve for "x". First, we apply the distributive property on the right side:


x\tan 25=30\tan 15+x\tan 15

Now, we substract
