Question

Write the trigonometry ratio for the triangle below.

Answer 1

see explanation

Explanation:

(a)

cosB =
`(adjacent)/(hypotenuse)` =
`(BC)/(AB)` =
`(a)/(c)`

(b)

tanA =
`(opposite)/(adjacent)` =
`(BC)/(AC)` =
`(a)/(b)`

(c)

sinB =
`(opposite)/(hypotenuse)` =
`(AC)/(AB)` =
`(b)/(c)`

Answer 2

cos B = a/c

tan A = a/b

sin B = b/c.

Explanation:

Sin = opposite / hypotenuse

cos = adjacent/ hypotenuse

tan = opposite/adjacent.
