What is the measurement of EF?

If necessary, round your answer to two decimal places, like this: 42.53

The measurement of EF is 1.98

Explanation:

Given that DEF is a right angled triangle.

Also, given that ∠E is a right angle, m∠D = 26° and DF = 4.5

We need to determine the measurement of EF.

The measurement of EF:

The measurement of EF can be determined using the trigonometric ratios.

Thus, we have,

where , and

Substituting the values, we have,

Multiplying both sides by 4.5, we get,

Also, given that sin 26° = 0.44

Thus, substituting the value, we get,

Thus, the measurement of EF is 1.98
