Triangle ABC ~ triangle DEF.

triangle ABC with side AB labeled 11, side CA labeled 7.6 and side BC labeled 7.9 and a second triangle DEF with side DE labeled 4.4

Determine the measurement of FD.

FD = 3.16
FD = 3.04
FD = 1.39
FD = 1.1

1 answer

To determine the measurement of FD, we can use the concept of similarity of triangles.

Since triangle ABC ~ triangle DEF, the corresponding sides are proportional.

FD/AB = DE/BC

FD/11 = 4.4/7.9

FD = (11*4.4)/7.9

FD = 61.6/7.9

FD ≈ 7.79

Therefore, the measurement of FD is approximately 7.79.

None of the provided options match this calculation, so there may be a mistake in the given values of the sides of the triangles.
