Question

What is the sine ratio of angle E?

A - 5/3
B - 3/5
C - 5/4
D - 4/5

Answer 1

sine: opposite divided by the hypotenuse

So, S = 6/10
S = 3/5

{B} is what I got.

Answer 2

The correct option is B.

Explanation:

In a right angled triangle

`\sin \theta=(perpendicular)/(hypotenuse)=(opposite)/(hypotenuse)`

In the given triangle DEF, the opposite sides of angle E is DF=6 units and hypotenuse EF=10 units.

The sine ratio of angle E is

`\sin E=(DF)/(EF)`

`\sin E=(6)/(10)`

`\sin E=(3)/(5)`

The sine ratio of angle E is 3/5, therefore the correct option is B.
