ANSWER

EXPLANATION
We want to factor

out of

The first term is already having a factor of

The constant term which is the second term is not having a factor of

so we need to use a trick of multiplying and dividing by the same factor to obtain,

We can now factor

out of the right hand side to obtain,

Let us rewrite the right most fraction using the normal division symbol.

We simplify to obtain,

This further gives us,

Answer:
The value of
is 10º.
Step-by-step explanation:
From Euclidean Geometry we remember that the sum of internal angles within a triangle equals to 180º. We present the resulting triangle after applying some geometric handling in the image attached below. Then, the triangle satisfies the following equation:
(1)


The value of
is 10º.
X = # of perfomances
y = total amount of money
Income: y = 7500x
Expense: y = 5900x + 88000
Substitution:
7500x = 5900x + 88000
1600x = 88000
x = 55
y = 7500(55) = $412,500
55 performances are needed to break-even.
