Question

Find the trigonometric ratio

Answer 1

Answer: 4/5

Explanation:

Sin ∅ =
`(opposite)/(hypotenuse)`

- opposite means, the length of the side opposite of the angle

-trig can only be sued in a right triangle, so the hypotenuse is always the side opposite of the right angle, or the longest side

Your question

sin A=
`(32)/(40)` you can reduce this ratio by 8, meaning you can divide the top and bottom by 8 to get a reduced fraction

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