triangle GHJ ~ triangle CDE. GH = 5 yards, HJ = 7.5 yards, CD = 9 yards. what is the length of DE?
To find the length of DE, we first need to set up a proportion using the corresponding sides of the two similar triangles:
GH / CD = HJ / DE
Substitute the given values:
5 / 9 = 7.5 / DE
Cross multiply to solve for DE:
5 * DE = 9 * 7.5
5DE = 67.5
DE = 67.5 / 5
DE = 13.5 yards
So, the length of DE is 13.5 yards.
