HELP ASAP PLZ??? You're in charge of the firewords display for the neighborhood party this year. Depending on the shell size the fireworks will explode at various heights. A 10-inch shell that is fired can reach a height of 1200 feet. If it is launched at an angle of 65°, how far away (x) would someone have to be sitting to be directly under the explosion? Round your answer to the nearest foot

there are many solutions.

step-by-step explanation:

step 1: simplify both sides of the equation.

4x+6=4x^2+10x−4

step 2: subtract 4x^2+10x-4 from both sides.

4x+6−(4x^2+10x−4)=4x^2+10x−4−(4x^2+10x−4)

−4x^2−6x+10=0

step 3: factor left side of equation.

−2(2x+5)(x−1)=0

step 4: set factors equal to 0.

x=-5/2 or x=1
