Question

Write the trigonometry ratio for the triangle below.

Answer 1

Answer:

see explanation

Step-by-step explanation:

(a)

cosB = $\frac{adjacent}{hypotenuse}$ = $\frac{BC}{AB}$ = $\frac{a}{c}$

(b)

tanA = $\frac{opposite}{adjacent}$ = $\frac{BC}{AC}$ = $\frac{a}{b}$

(c)

sinB = $\frac{opposite}{hypotenuse}$ = $\frac{AC}{AB}$ = $\frac{b}{c}$

Answer 2

Answer:

cos B = a/c

tan A = a/b

sin B = b/c.

Step-by-step explanation:

Sin = opposite / hypotenuse

cos = adjacent/ hypotenuse

tan = opposite/adjacent.
