Rectangles ABCD and EFGH are similar figures because angles A, B, C, and D are congruent to angles E, F, G, and H, respectively.

If DA equals 19 units, AB equals 8 units, and HE equals 133 units, what does EF equal?

A. 56 units
B. 122 units
C. 7 units
D. 315.88 units

  • Math -

    DA/HE = AB/EF, so

    19/133 = 8/EF
    EF = 56
