In quadrant I, when sin angle is 1/2, cos angle is (sqrt3)/2
The answer for the first one is 48 fluid ounces
Ok so say you have I don't 266÷12 so you would round 266 to 700 hundred and 12 to ten and you would divided 700 by 12
Hope this helped :-)
Angles that are complementary end up equally 90 degrees. That means 30 degrees is one and 60 is the other because 30*2 = 60
60+30=90
