Question

What is SIN A?

Question 4 options:

3/4


4/3


3/5


4/5

Answer 1

`\sin A =(4)/(5)`

Explanation:

Recall the mnemonics SOH CAH TOA.

SOH means the Sine ratio is Opposite over Hypotenuse.

This implies that;

`\sin A =(Opposite)/(Hypotenuse)`

The side opposite to angle A is 4cm and the hypotenuse is 5cm.

`\therefore \sin A =(4)/(5)`
