Question

please solve it . trigonometry​

Answer 1

Answer:

Step-by-step explanation:

4tan = 3 ⇒ tan = 3/4

we know, tan = perpendicular/base

so, after comparing , perpendicular = 3 and base = 4

∴ hypotenuse = √(3² + 4²) = 5

now, sin = perpendicular/hypotenuse = 3/5

cos = base/hypotenuse = 4/5

now, (4sin - cos + 1)/(4sin + cos - 1)

= (4 × 3/5 - 4/5 + 1)/(4 × 3/5 + 4/5 - 1)

= (12 - 4 + 5)/(12 + 4 - 5)

= 13/11

Answer 2

Answer:

13/11
