WebMar 26, 2016 · When you draw an altitude to the hypotenuse of a right triangle, you create two right triangles that are similar to each other and to the original right triangle. Because these triangles are similar, you can set up proportions relating the corresponding sides.

WebApply Theorem 2 on Proportionality. AB/AC = BD/DC Substitute. 9/15 = (14 - x)/x 3/5 = (14 - x)/x Multiply both sides by 5x. 5x ⋅ (3/5) = [ (14 - x)/x] ⋅ 5x 3x = 70 - 5x Add 5x to each side. 8x = 70 Divide both sides by 8. x = 8.75 Hence, the length of DC is 8.75 units. 6. Answer : WebSo you could say that the ratio of 9 markers to the cost of 9 markers, so the ratio of the number of markers, so 9, to the cost of the 9 markers, to 11.50, this should be equal to the ratio of our new number of markers, 7, to whatever the cost of the 7 markers are, to x. Let me do x in green. So this is a completely valid proportion here.
