Question

I WILL GIVE 20 POINTS TO THOSE WHO ANSWER THIS QUESTION RIGHT NOOOO SCAMS AND EXPLAIN WHY THAT IS THE ANSWER

Answer 1

`\sf \sin A=\boxed{(5)/(13)}\quad\cos A=\boxed{(12)/(13)}\quad\tan A=\boxed{(5)/(12)}`

Explanation:

Trigonometric ratios

`\sf \sin(\theta)=(O)/(H)\quad\cos(\theta)=(A)/(H)\quad\tan(\theta)=(O)/(A)`

where:

• 
  `\theta` is the angle
• O is the side opposite the angle
• A is the side adjacent the angle
• H is the hypotenuse

Given:

• 
  `\theta` = A
• O = BC = 5
• A = AC = 12
• H = AB = 13

`\implies \sf \sin A=(5)/(13)\quad\cos A=(12)/(13)\quad\tan A=(5)/(12)`
