kondaur [170]

Answer:

Step-by-step explanation:

using the rule of radicals

$\sqrt{a}$ × $\sqrt{b}$ ⇔ $\sqrt{ab}$ , hence

$\sqrt{-12}$

= $\sqrt{4(3)(-1)}$ = $\sqrt{4}$ × $\sqrt{3}$ × $\sqrt{-1}$ [ $\sqrt{-1}$ = i]

= 2i $\sqrt{3}$ → E

Use the cosine ratio or the inverse cosine to solve for x. Round your answer to the nearest tenth.

maria [59]

Answer:

x ≈ 12.6 m

Step-by-step explanation:

By using cosine ratio in the given right triangle RTS,

cos(S)° = $\frac{\text{Adjacent side}}{\text{Hypotenuse}}$

cos(33)° = $\frac{\text{ST}}{\text{SR}}$

cos(33)° = $\frac{x}{15}$

x = 15.cos(33)°

x = 12.58

x ≈ 12.6 m

Therefore, measure of side ST = 12.6 m is the answer.
