Question

Given right triangle def what is the value of sin e

Answer 1

right triangle
10^2 - 8^2 = 100 - 64 = 36
DF = √36
DF = 6
so
sinE = Opp / Hypo
sinE = 6/10
sinE = 3/5

Answer 2

Explanation:

From the given triangle DEF, we have

`(EF)^(2)=(ED)^(2)+(DF)^(2)`

`(10)^(2)=(8)^(2)+(DF)^(2)`

`100-64=(DF)^2`

`DF=6`

Now, we know that SinE=
`(Perpendicular)/(Hypotenuse)`, thus

`SinE=(DF)/(EF)`

`SinE=(6)/(10)=(3)/(5)`

Therefore, the value of SinE is
`(3)/(5)`.
