Answer:
x = 33.8°
Step-by-step explanation:
The resulting diagram we have is a right triangle. To find x, apply trigonometric function.
Reference angle = x
Opposite = 116
Adjacent = 173
Apply TOA:
Tan x = Opp/Adj



x = 33.8° (nearest tenth)

<u>Corrected Question</u>
In the year 2009, the cost of a flat screen television can be modeled by the equation C = -10t^2 + 500 where t is the number of years since 2009. Factor this cost polynomial.
Answer:

Using express exponents, you write C=10(50-t^2)
Step-by-step explanation:
To factor the cost polynomial,
, we follow these steps.
Step 1: Determine the greatest common divisor of the terms in the polynomial
The terms in the polynomial are 
The greatest common divisor of
is 10.
Step 2: Factor the polynomial by dividing each of the terms with the greatest common divisor obtained above.
