Answer:
Total height of kite above ground = 4.8m
Step-by-step explanation:
Let h = height
Let d = length of string
Angle = 30 degrees
string = 8m
sin(θ) = [tex]\frac{opp}{hyp}[/tex]
sin(30) = [tex]\frac{h}{8m}[/tex]
[sin(30) = [tex]\frac{1}{2}[/tex]]
[tex]\frac{1}{2}[/tex] = [tex]\frac{h}{8}[/tex]
cross multiply
2h = 8
h = 4 meters
80 cm = 0.8 meters
Total height of kite = 4m + 0.8m = 4.8m
