Question

The length of a string between a kite and point on the ground is 90m. The string makes an angle of 60° with the level of ground. assuming that there is no slang in the string. Find the height of the kite​

Answer 1

Step-by-step explanation:

sin60=h/90

h=90×√3/2

=45√3m

Answer 2

Answer:

tan theta = AB/AC →15/8 = H/BC

BC= 84/15 → (1)

IN triangle ABC by Pythagoras theorem

AC^2= BC^2 + AB^2

90^2=(8H/15)^3+ H^2

90^2= (8H^2) + (15H)^2/ 15^2

H^2 (8^2+15^2)= 90^2×15^2

H^2=(64+225)= (90×15)2

H^2= (90×15)2/17

H= 90×15/17 = 79.71
