Answer:

The required value is 5

Step-by-step explanation:

4sinθ = 3cosθ

4sin2θ - 3cos2θ + 2  = 4 (2sinθcosθ) - 3 (2c0s²θ -1) + 2

                                  = 4 sinθ x 2cosθ - 6 cos²θ +3 +2

                                  =  (3cosθ )x 2cosθ - 6cos²θ + 5

                                  = 6 cos²θ - 6cos²θ +5

                                  = 5
