The rate of the slower jet is 672 miles per hour.
The rate of the slower jet is 752 miles per hour.
<h3>How to find the rate of the jets?</h3>
Two jets leave an air base at the same time and travel in opposite directions.
One jet travels 80 mi/h faster than the other.
let
x = rate of the slower jet
faster jet = 80 + x
Therefore,
rate = distance / time
The two jets are 11392 miles apart.
(80 + x)8 + 8x = 11392
640 + 8x + 8x = 11392
640 + 16x = 11392
16x = 11392 - 640
16x = 10752
divide both sides by 16
x = 10752 / 16
x = 672 miles per hour
rate of the faster jet = 80 + 672 = 752 miles per hour

This is the rule of sums of trig identities. It says that sin(a + b) = sina*cosb+sinb*cosa. Set up your right triangles. In a 30-60-90 triangle, the side across from the 60 angle is the square root of 3, the side across from the 30 is 1, and the hypotenuse is 2. In a 45-45-90 the sides across from the 45 degree angles are 1 and the hypotenuse is square root of 2. With that being said, the sin of 60 is

and the cos of 60 is 1/2. Both the sin and cos of 45 is

. So your formula is filled in like this:

. When you do the multiplication on those sets of parenthesis, you get

. When you add those your solution is

. Depending upon your instructor you may have to rationalize that denominator to get that radical out from under there, but if not, that's pretty much it!
Is there arc length or may be radius
Don't cry!! You got this! Just take it one step at a time and list your known values:
h = 5 m
r = 5 m
The volume of a cone is V = (1/3)πr^2h
V = (1/3)(3.14)(5)^2(5) = 130.83 m^3
I believe in you! I hope this helps!
