Answer:
B.) 51/64
Step-by-step explanation:
Okay so make a coordinate plane, insert the numbers in the right place, then count what’s in between, you got this, I’ll totally help you if you didn’t get it.
Because you if it changes its a function
Answer:
cot theta = -√3
Step-by-step explanation:
we are given that cos theta = - √3/2 within the range 180° < theta < 270° and
since cos theta = adj/hyp
adj = - √3
hyp = 2
Get the opposite using the pythagoras theorem
hyp^2 = opp^2 + adj^2
2² = opp² + (-√3)²
4 = opp² + 3
opp² = 4-3
opp² = 1
opp = 1
tan theta = opp/adj
tan theta = - 1/√3
Recall that cot theta = 1/tan theta
cot theta = 1/(-1/√3)
cot theta = -√3
3/8 + 5/2
=3/8 + 20/8
= 23/8
or
= 2 7/8
