Question

plz plz give me the correct answer ​

Answer 1

Answer:

sin = 12/17 because when we find perpendicular of triangle we get p = 12 then sin = P/H = 12/17

Answer 2

Answer:

here is your answer

Step-by-step explanation:

4. cos 45°=1

sin30°=1/2

(1)^2+(1/2)^2

1+1/4

4+1/4

5/4

5. cosΦ=15/17=b/h

by Pythagoras theorm to find p

h^2=p^2+b^2

(17)^2=p^2+(15)^2

p^2=289-225

p=√64

p= 8

sinΦ=p/h

sinΦ=8/17

hope it help ☺☺
