Calculating Critical angle PLEASE HELP
sin90°/sinθ = 1.61

I guess you could also do this by finding the intersection of (x-6)^2 + (y-6)^2 = 36 and y=x the answers are the same.

equidistant from the x,y axes means that if (x,y) is one point, y=x or y=-x on the line y=x, if the distance from (6,6) is 6, then the x- and y-distances are ±6/√2. So, (6-6/√2,6-6/√2) and (6+6/√2,6+6/√2) are two such points. Points on the ...

(h+1250)/1150 = tan 52°
algebra
just solve it like any quadratic. When it hits the ground, h=0, so 4 + 60t - 16t^2 = 0 t=3.8 sec this doesn't factor easily, so the quadratic formula is probably best. However, while you're doing that, the kicker has probably scored a goal!

well, how long does it take to fall 4m? divide that into 6m to get the speed.

It helps to know that Exit 16 is east of Exit 17. Since the two cars travel 7km in t seconds, 30t + 26t = 7000 t = 125 sec That would be 2'5"

surely you know that the circle contains 360°. So, (8x-10) + (6x) + (10x+10) = 360 x = 15
