Quinn did not make a mistake. This is because everything she did is correct and also if we calculate the expression without doing anything she did, we see that she has the right answer.
X = 56 degrees because the sum of all the angles in a triangle is 180 degrees.
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:

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

Now, we take the tangent of 15:

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

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

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

Now, we substract
