Question

Given the right angle triangle shown here, calculate:

Answer 1

The first answer is correct

Answer 2

Answer:

see explanation

Step-by-step explanation:

(1)

(a)

sin(a) = $\frac{opposite}{hypotenuse}$ = $\frac{15}{17}$

(b)

cos(a) = $\frac{adjacent}{hypotenuse}$ = $\frac{8}{17}$

(c)

tan(a) = $\frac{opposite}{adjacent}$ = $\frac{15}{8}$

----------------------------------------------------

(2)

(a)

sin(b) = $\frac{opposite}{hypotenuse}$ = $\frac{8}{17}$

(b)

cos(b) = $\frac{adjacent}{hypotenuse}$ = $\frac{15}{17}$

(c)

tan(b) = $\frac{opposite}{adjacent}$ = $\frac{8}{15}$
