Question

What is the answer to this

Answer 1

sinE = $\frac{3}{5}$

the sine ratio is defined as

sin( angle ) = $\frac{opposite}{hypotenuse}$

here the opposite to ∠E is 6 and the hypotenuse is 10

sinE = $\frac{6}{10}$ = $\frac{3}{5}$

Answer 2

$S\frac{O}{H} C\frac{A}{H} T\frac{O}{A}$ or $Sin\frac{Opposite}{Hypotenuse}Cos\frac{Adjacent}{Hypotenuse} Tan\frac{Opposite}{Adjacent}$

At the point/angle E:

- the adjacent side(side next to the point/angle) is ED

- the opposite side(side of the triangle across from the point/angle) is DF

- the hypotenuse (the longest side of the triangle) is EF.

sin ∠E = $\frac{opposite}{hypotenuse}$

sin ∠E = $\frac{6}{10} = \frac{3}{5}$ (simplified)
