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:
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
