Question

In ΔDEF, the measure of ∠F=90°, ED = 65, FE = 56, and DF = 33. What is the value of the sine of ∠D to the nearest hundredth?

Answer 1

Answer:0.86

Explanation:

Answer 2

Sine(D)=>0.861

m∠D= 59.42°

Explanation:

Given:

ED = 65

FE = 56

DF = 33

In the right triangle DEF

Sine(D)= Perpendicular / hypotenuse => FE / ED

Sine(D)= 56/ 65 =>0.861

m∠D=
`sin^(-1)`(56/65)

m∠D= 59.42°
