PLEASE HELP ASAP A weir is a dam that is built across a river to regulate the flow of water. The flow
rate Q (in cubic feet per second) can be calculated using the formula Q = 3.3674h3/2,
where l is the length (in feet) of the bottom of the spillway and h is the depth (in feet)
of the water on the spillway. Determine the flow rate of a weir with a spillway that is
20 feet long and has a water depth of 5 feet. Round your answer to the nearest whole
number

let ratio 6:4:2 be 6x,4x and 2x

we have

6x+4x+2x=180 sum of interior angle of the triangle is 180

12x=180

x=180/12=15

Step-by-step explanation:

missing Angle are

6x=6×15=90°

4x=4×15=60°

2x=2×15=39°
