Question

Use the information below to find EF such that ABC ~ DEF.

AB = 36, BC = 24, DE = 48, B= 110 angle E = 110 angle, EF = ?

A.32
B.36
C.68
D.72

Answer 1

well if the triangles are similar then use the ratio of corresponding sides to find EF

so its

\[\frac{DE}{AB} = \frac{EF}{BC}\]

then

\[\frac{48}{36} = \frac{EF}{24}\]

hope it helps
