Question

please explain how to do this

Answer 1

Answer:

27.4

Step-by-step explanation:

Use your calculator for this.

Remember, use SOH CAH TOA

We have an opposite (O) and an adjacent side (A), so we use SINE

sin(41)=18/X......following?

Now, solve for X by multiplying both sides by X......sin(41)(X)=18

Then, divide both sides by sin(41).

Type into your calculator: 18/sin(41), and you'll get 27.44. Round to the nearest tenth, or 27.4!

Answer 2

Answer:

x = 11.8

Step-by-step explanation:

sine = $\frac{opposite}{hypotenuse}$

⇒ sine 41 = $\frac{18}{x}$

⇒ 0.656 = $\frac{18}{x}$

multiply 18 on both sides:

⇒ 0.656 x 18 = $\frac{18}{x}$ x 18

⇒ 11.808 = x

round to the nearest tenth:

⇒ 11.808 = 11.8
