Question

I NEED HELP PLEASE HELP. SHOW ME HOW YOU DID IT

Answer 1

Sin = - 4/8

Quadrant IV = only cosine is positive

a = height (4)
b = base ( 8^2-4^2=b^2
b = 6.93 @
$\sqrt{48}$

c = hypothenuse(8)

cos =
$\sqrt{48}$
/8

tan = - 4/
$\sqrt{48}$

sec = 1/cos
1/cos = 1/ (
$\sqrt{48}$
/8)
sec = 8/
$\sqrt{48}$

csc = 1/sin
1/sin = 1/(-4/8)
csc = - 2

cot = 1/tan
1/tan = 1/(-4/
$\sqrt{48}$
)
cot = -
$\sqrt{48}$
/4
