Which equation can be used to find the value of x if the shortest side, y, measures 2.1 m? 2 x minus 2.1 equals 7.5 4.2 plus y equals 7.5 y minus 4.2 equals 7.5 2.1 plus 2 x equals 7.5

step-by-step explanation:

if you meant, "on the way from (3, 2) to (3, 14):

x does not change; y increases by 12.

call the larger triangle abc

then the smaller triangle cde is similar to abc (all angles are equal, aaa).  

ab is the side that is 36, and we wish to find de, the side corresponding to ab

area_cde = area_abc - area_cde --> area_abc / area_cde = 2

let x=length of de

ratio of areas = (ratio of sides)^2
