On #31 is it a 30,60,90 triangle?
We aren't given that it's a 30-60-90 triangle. Only that it's a right triangle (see the little box in the angle?).
Also how do you set it up?
If you are given two sides of a right triangle and are asked to find the third, what fabulous formula can you use?
And homework worksheet #3 #'s 51,52, and 53 what formula do you use to start these problems? You are asked to find the DISTANCE between points A and B. You can use that formula, or you could draw on the graph a triangle using AB as the hypotenuse...then you could use our favorite formula from #31 above! Give it a shot and see how you do!
Good questions, Courtnie. I've answered each of them above. If you're still stuck, come in tomorrow morning at 7:30 and we can put them on the board!
