In here, we could write an equality as x – 12 < 65. In solving inequalities, we follow the same rule as solving algebraic expressions. We will transpose 12 to the other side, giving us x < 65 + 12. Simplifying, we have x < 77. Geraldo must have a bill less than $77 in order for him not to spend more than $65.

Draw a right triangle.

$tan(theta) = \frac{opposite}{adjacent}$

$tan(theta) = \frac{10}{14}$

Arctangent (tan^-1) can be used to find theta.

$tan^{-1}(\frac{10}{14})=theta$

$theta\ is\ approx\ \boxed{36\ degrees}$
