the answer is 1 and 4
Start by subtracting, so on #1 subtract 5-8, 8-11, 11-14
then go up to x, -2--1, -1-0, 0-1
Answer:
<em>18.2°, 161.8° and 378.2°</em>
Step-by-step explanation:
Given the expression:
8 sin x = 2.5
Divide both sides by 8
sinx = 2.5/8
Sinx = 0.3125
x = arcsin(0.3125)
x1 = 18.2
Since sin theta is positive in the second quadrant, x2 = 180 - 18.2 = 161.8°
Since our angle must lie in between 0° and 720°,then;
x3 = 360 + 18.2 = 378.2°
<em>Hence the required angles are 18.2°, 161.8° and 378.2°</em>

Answer:
51 minutes!
Step-by-step explanation:
<em>Hello there fellow human!</em>
First off, you convert kilometers to miles.
1 kilometer = 0.62 miles; therefore, 8 kilometers = 8*0.62 = 4.96 miles
Next, you determine how many minutes it takes for John to cover 1 mile
which is gotten by dividing 41 by 4;
41 / 4 = 10.25. So it takes 10.25 minutes to cover 1 mile. (minutes per mile)
Next, you multiply the number of minutes taken to cover <em>1 mile (10.25)</em> by <em>4.96 miles (8 kilometers)</em>, 10.25 * 4.96 = 50.84 minutes. Rounding that to the nearest minute, you get 51 minutes which make sense because the amount of time taken to cover 4 miles (41 minutes) will be shorter than the time taken to cover 4.96 miles (50.84 minutes) since 4 miles is smaller than 4.96 miles.

All calculations where done with a calculator. If you don't have that, you can always divide manually and convert to fraction.
It should be the third option
