We have 1 m = 100cm
⇒ 72 m = 7200 cm
⇒ 7200 / 1.5= 4800 cm = 48 m
You did the top right but the denominator is 0 so the slope in undefined or 0.
Hope this helps!
Answer: Height of tree = 26 ft
Make a triangle ABC with 40 degrees angle. The shadow is the base of the triangle equals 31 feet.
Base = AC = 31
Perpendicular = CB = ?
Hypotenuse = AB
Using trigonometric equation
tan 40 (deg) = CB / AC
CB = Tan 40 x AC
CB = 0.83909 x 31
CB = 26.011
Thus the height of the tree = 26 ft
parallel = same slope
y=1/5x-4
slope= 1/5x
solve using for b using y=mx+b
-4=(1/5)(5)+b
-4=4+b
(subtract -4 from both sides)
-8=b
put your equation together:
y=1/5x-8
cos0 = √3/2
1 - cos²0 = sin²0
= 1/4 = sin²0
sin in quadrant 4 is negative
sin0 = -1/2
