<h2>
Answer:</h2><h2>
The kite is 186.75 metres from the ground</h2>
Step-by-step explanation:
The length of the string, hypotenuse = 225 m
Angle of elevation, θ = 56°
Sine of an angle is the ratio of the opposite side over the hypotenuese.
Sin θ =
substitute the values in the formula,
Sin 56° = 
h = 225 (Sin 56°)
= 225 (0.83)
= 186.75 metres
The kite is 186.75 metres from the ground
Answer:
D) 12%
Step-by-step explanation:
The merchant marks his wares 40% more than the real price.
The merchant also allows 20% discount.
Let the real price = 100
After a 40% mark up, the price becomes
(40 /100) * 100
= 40
So we have 100 +40= 140
Discount of 20% = (20/100)* 140
= 28
The price is 140 - 28 = 112
Profit = 112 -100
= 12%
