What is the value of x to the nearest tenth

marishachu [46]

You will have to use trig to solve this:

The side you have is adjacent to the known angle

The side you are looking for is opposite the known angle

^^^This means you need to use tan:

tan(24) = $\frac{x}{12}$

.445222 = $\frac{x}{12}$

^^^input tan(24) into calculator, then multiply 12 to both sides to isolate and solve for x

5.3 ≈ x

Hope this helped!

Dan pays £714.73 a year on his car insurance

LenaWriter [7]

Answer:

The Current Insurance cost = $685.43

Step-by-step explanation:

Given that Dan pays £714.73 a year on his car insurance.

Reduced Percentage = 4.1%

Reduced Amount = 4.1% × 714.73

= [4.1 / 100] × [714.73]

= 0.041 × 714.73

= $29.30

The current cost can be calculated by subtracting the reduced amount of 29.30 from 714.73.

Current Insurance cost = 714.73 - 29.30

= $685.43

Therefore, the Current Insurance cost = $685.43
