2 trig ratios missing sides and angels

ivanzaharov [21]

Answer:

Step-by-step explanation:

Using the cosine ratio in the right triangle.

cos66° = $\frac{adjacent}{hypotenuse}$ = $\frac{13}{x}$ ( multiply both sides by x )

x × cos66° = 13 ( divide both sides by cos66° )

x = $\frac{13}{cos66}$ ≈ 32.0 ( to the nearest tenth )

sergiy2304 [10]

Answer:

$7x^3-2x^2-5$

Step-by-step explanation:

We need to add the two terms.

$(6x^3+3x^2-2)+(x^3-5x^2-3)$

Solving,

Combine the like terms and adding those terms

$(6x^3+3x^2-2)+(x^3-5x^2-3)\\=6x^3+3x^2-2+x^3-5x^2-3\\=6x^3+x^3+3x^2-5x^2-2-3\\=7x^3-2x^2-5$

So, the answer is:

$7x^3-2x^2-5$
