Question

Triangle ABC ~ triangle DEF. Use the image to answer the question.

Determine the measurement of EF.

EF = 1.1
EF = 1.39
EF = 2.37
EF = 3.3

Answer 1

EF = 2.37

Explanation:

It's given that these are similar triangles.

In similar triangles, the side lengths are proportional.

We can write the following equation based on this information:

`(11)/(3.3) = (7.9)/(ef)`

• Cross multiply fractions

11EF = 27.03

• Divide both sides by 11

EF = 2.37
