प्रयुक्त सूत्र:

tan θ =

तन θ =

गणना:

2(sinθ + cosθ ) = 3(sinθ - cosθ)

2 sinθ + 2cosθ = 3 sinθ - 3 cosθ

5 cosθ = sinθ

= 5

tanθ = 5

अब, लंब = 5 और आधार = 1

पाइथागोरस प्रमेय का प्रयोग करके,

H2 = P2 + B2

H2 = 25 + 1

H = 

अब, sinθ  = P/H और cosθ  = B/H

sinθ  = 

cosθ = 

प्रश्न के अनुसार,

= ( ) 4 - ( ) 4

-

=

=

∴ सही उत्तर है।
