Dahasolnce [82]

Answer:

Step-by-step explanation:

Let's start by crossing everything out!

12/3 can be crossed out to 4.

a^3/a^2 can be crossed out to a.

b^6/b^4 can be crossed out into b^2.

c^5/c^5 is just 1.

So which the results we got, we can multiply them, so that it is 4ab^2.

4ab^2 is our final answer!

Answer:

WX = 7.9

Step-by-step explanation:

By applying tangent rule (law of tan) in the given right triangle WXY.

tan(W) = $\frac{\text{Opposite side}}{\text{Adjacent side}}$

tan(27)° = $\frac{\text{XY}}{\text{WX}}$

0.509525 = $\frac{4}{\text{WX}}$

WX = $\frac{4}{0.509525}$

WX = 7.85

WX ≈ 7.9

Therefore, length of side WX is 7.9 units.
