[tex] \displaystyle \: \bf \: \implies \: Tan \: θ \: = \: \frac{Opposite \: side}{Adjacent \: side} [/tex]
[tex] \: \bf \implies \: Hypotenuse^{2} \: = \: Base^{2} + Height^{2} [/tex]
Given,
[tex]⇝[/tex]A kite flies in the sky with a thread of 68m and makes an angle θ
[tex]⇝[/tex]Tan θ = 15/8
We know that,
[tex]\displaystyle \: \sf \: \implies \: Tan \: θ \: = \: \frac{Opposite \: side}{Adjacent \: side} [/tex]
[tex]\displaystyle \: \sf \: \implies \: Tan \: θ \: = \: \frac{15}{8} [/tex]
Let,
By Pythagoras Theorem,
[tex] \: \sf \implies \: Hypotenuse^{2} \: = \: Base^{2} + Height^{2} [/tex]
[tex] \: \sf \implies \: (68)^{2} \: = \: (8x)^{2} + (15x)^{2} [/tex]
[tex] \: \sf \implies \: 4624\: = \: 64 x^{2} + 225x^{2} [/tex]
[tex] \: \sf \implies \: 4624\: = \: 289x^{2} [/tex]
[tex] \displaystyle \: \sf \implies \: \cancel\frac{4624}{289} \: = \: x^{2} [/tex]
[tex]\displaystyle \: \sf \implies \: \frac{16}{1} \: = \: x^{2} [/tex]
[tex]\displaystyle \: \sf \implies \: 16 \: = \: x^{2} [/tex]
[tex]\displaystyle \: \sf \implies \: 4 \: = \: x[/tex]
[tex]\displaystyle \: \bf \implies \: x \: = \: 4[/tex]
Hence,
∴ Height of kite from the ground = 15(4) = 60m
