Answer 1

Answer:

1. sinx = 8/17

2.cosy =6/10=3/5

3.

Answer 2

Step-by-step explanation:

for finding the base use Pythagoras theorem

(base)^2+(8^2)= 17^2

base^2 = 289-64 = 225

base = 15

(i)sin x° = perpendicular/ hypo

8/17

now find hypo for angle y

6^2 + 8^2 = hypo^2

36+64 = hypo^2

hypo = 10

(ii)cos y° = base/hypo

6/10 = 3/5

now tanx° = perpendicular/base

8/15

sin y° = perpendicular/hypo

8/10

cos y ° we have from (ii)

3(8/15)-2(8/10)+4(3/5)

8/5-8/5+12/5

12/5
