B) 48 degrees
first add 52 and 59 then subtract from 180 to get angle y (which is 69)
then since all triangles haves all 3 interior angles add to 180 degrees, add 69 and 63 (which is 132) and subtract from 180 to get the missing angle of x (which is 48 degrees)

Answer:
80°
Step-by-step explanation:
140+140+x=360
280+x=360
x=80
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
you need to find to find the value of x and y.
2x>(-15-5y)
x>(-15-5y)/2
now put this in to other equation and solve for y and then put the y value in and find x.
