Answer:
.
Step-by-step explanation:
We are told that a man drove x miles per hour for 3 hours, so he traveled 3x miles in three hours.
We are also told that he drove (2x-60) miles per hour for the next 4.75 hours. So The distance traveled by in next 4.75 hours will be:
To find the total distance traveled by man we will add distances traveled by him in first 3 hours and next 4.75 hours.
Upon combining like terms we will get,
Therefore, the total distance traveled in terms of x will be .
Answer:
<h2>49.5°</h2>Step-by-step explanation:
Given the trigonometry function as shown sin W = 0.79, to get W, the following steps must be followed.
Step 1: Take the arcsin of both sides of the equation
Step 2: Use a calculator to get the resulting value of W
(to nearest tenth of a degree)
This gives the acute angle needed.
Note that acute angle are angles that are less than 90°
