Answer:
AB = 185.77 feet
Step-by-step explanation:
From the figure attached, in ΔABC,
m∠B = 103.2°, m∠C = 14.4° and side BC = 661 feet
We have to find the measure of side AB.
Since ∠A + ∠B + ∠C = 180°
∠A + 103.2 + 14.4 = 180
∠A + 117.6 = 180
∠A = 180 - 117.6
= 62.4°
By applying sine rule in the given triangle ABC



AB = 
= 185.77 feet
Therefore, AB = 185.77 feet will be the answer.

<u>Algebraic Operations
</u>
Some basic rules must be fresh in our minds when trying to simplify complex algebraic expressions. For example, the power rule respect to the product or quotient:



Let's face the questions at hand
8. A number is raised to a negative exponent is negative?
Following the expressions recalled above, let's pick the expression

This is a negative power resulting in a positive number
Now we pick

This time, the negative power leads to a negative result, so it doesn't matter the sign of exponent to determine the sign of the result
<em>Answer: C sometimes
</em>
9 simplify(4xy^2)^3(xy)^5



10 simplify(2t^-3)^3(0.4r)^2
