1) for this type of exercise you must, add the amounts of miles to know the total number of miles traveled by Paul
(1/8 + 1/4 ) = 1+2/8 = 3 /8 = 0,375 miles . the total number of miles traveled by Paul is 0,375 miles
Using trigonometry
tan(x)=9/6
use your calculator to find x using tan-1(9/6) and you get 56.3° which is basically the first answer
We know that : Sin²θ + Cos²θ = 1
Given : Sinθ
Given : θ lies in Quadrant II
We know that : Cosθ is Negative in Quadrant II
Option 3 is the Answer
0.2*0.2*0.2=0.008 cubic inches
