Question

tan x = 4/3, find 4sin^2x p - 3cos^2x + 2

Answer 1

Answer:

Step-by-step explanation:

sin = 4/5

cos = 3/5

now find 4 sin ^ 2 x + 3 cos ^ 2 x +2

4 (4/5)^2 - 3 (3/5)^2 +2

64/25 - 27/25 + 2

64- 27+50 / 25

87/25

Answer 2

Answer:

87/25

Step-by-step explanation:

tan x = 4/3

From the triangle attached below, sin x = 4/5 and cos x = 3/5

= 4sin²x - 3cos²x + 2

= 4×16/25 - 3×9/25 + 2

= 64/25 - 27/25 + 2

= 37/25 + 2

= 87/25
