Answer:

B.

Step-by-step explanation:

sin∅ = opposite side over hypotenuse

cos∅ = adjacent side over hypotenuse

To find <em>x</em>, there are multiple ways:

tan72° = 6/x

x = 6/tan72°

cos72° = x/15

15cos72° = x

I need help with Rational Functions
Andrej [43]

Answer: (5a+b)/2

Step-by-step explanation:

1. First factor 5a^2+36ab+7b^2

=(5a+b)(a+7b)

2. Factor 2a+14b

The two can be factored out, making the equation equal to 2(a+7b).

The factored out equation is now \frac{(5a+b)(a+7b)}{2(a+7b)}

Since there is an (a+7b) on both sides of the fraction, they cancel out. You are left with (5a+b)/2. This fraction cannot be simplified more.

To verify you can multiply (5a+b)/2 times (2a+14b). If it is correct, it should come back out as 5a^2 + 36ab +7b^2
