Since it’s supplementary the straight line would equal to 180 degrees
4d - 1 + 105 = 180
4d + 104 = 180
4d = 76
d = 19

| <height=40 feet(a)
|
|______<base=60 feet(b)
c^2=a^2+b^2
c^2=40^2+60^2
c^2=5200 feet^2
c=(5200)^(1/2)
c=72.11102551 feet
Create equations:
10X+15y=2575.
X+Y=210.
Solve for X: X=210-Y, and sub it into the other equation: 10(210-Y)+15Y=2575. Solve for Y: 2,100-10y+15y=2575, 5y=475, y=95.
Sub Y into the original problem: X+95=210. Solve: X=115.
