The dependent is the one that you score and the independent is the number of the ones you answer correctly.Hope it helps :)
Answer:
1738.67 feet
Step-by-step explanation:
Imagine a right angles triangle, with the base length of 1800ft and the angle between the base and the hypotenuse to be 15 degrees.
Now, we have to calculate the hypotenuse length, using trigonometric ratios
The ratio that links adjacent side and hypotenuse is cos
So, write an equation:
cos(15) = Adjacent/Hypotenuse = 1800/H
Rearrange to solve.
H = cos(15) x 1800 = 1738.67
This is the distance flown by the aeroplane .
Hope this helps
To avoid multiplying the two numbers and then finding the cube root, find the cube root of each number first. the cube root of 27 is 3x3x3, so you can take out the three to outside of the sqrt, to get 3 cube root 18. eighteen does not have a cube root, so that's all you have to do. the answer would be 3 (cube root) 18.
