Answer:
B = 62.9ft
Step-by-step explanation:
The distance where she is from the oak tree is 75ft,
The angle of elevation the stone makes with the top of the oak tree is 40°
The height of the tree is x ft
See attached document for better illustration
Using SOHCAHTOA,
Tanθ = opposite/ adjacent
θ = 40°
Opposite = x ft
Adjacent = 75ft
Tan40 = x / 75
X = 75 × tan40
X = 75 × 0.8390
X = 62.92ft
The height of the oak tree is 62.9ft
That was said oddly. From what I understand, she would need to buy 64 feet of fabric.
Answer:
4/15
Step-by-step explanation:

If x is equaled to 10 then you will place 10 into 3 and it would look like this 3(10) + 5y= 20 now your next step is to multiply 3•10=30 so 30+5y=20 now all you have to do is 20- (-30)= -10 and then divide by 5 and it’s equal to -10/5= -2
29000 x 0.04 = 1,160
29000 - 1,160 = answer
27,840 = answer
