Question

Triangle D E F is shown. Angle E D F is a right angle. The length of D E is 8 and the length of hypotenuse E F is 10. Given right triangle DEF, what is the value of sin(E)? Three-fifths Three-fourths Four-fifths Four-thirds

Help please!!!

Answer 1

Answer:

Three-fifths

Step-by-step explanation:

Sin(E) = opposite/hypotenuse

DE is the base/adjacent, EF is the hupotenuse

DF if the opposite/perpendicular use pythagoras theorem to find DF:

10² = DF² + 8²

100 = DF² + 64

DF² = 36

DF = 6

Sin(E) = DF/EF

= 6/10 = 3/5 = 0.6
