Question

the length of a string attached to a kite and a point on the ground is 58m. If the string makes an angle A with the ground such that tan A=20/21, at what height is the kite​

Answer 1

Answer:

40 m

Step-by-step explanation:

it forms a right angled triangle with the string as hypotenuse

so the night ÷ base = 20/21

According to pythagoras hypotenuse ^3 =hight^2 +base^2

therefore 20^2 +21^2 = 841

square root of 841 = 29

as the length of the string is double of it

58÷29=2

the hight must be double the hight of the triangle

20 ×2 =40 m
