Question

please answer please i will definately mark the good answer as brainlieist​

Answer 1

3 cos A = 4 sin A => tan A = 3/4 , sin A = 3/5, cos A = 4/5, cot A = 4/3, cosec A = 5/3. cos A = 4/5. 3 - cot A + cosec A = 3 - 4/3 + 5/3 = 10/3.

Answer 2

we have,

4sinA = 3

sinA = 3/4

p/h = 3/4

Perpendicular = 3 units

&

hypotenuse = 4units.

Using Pythagoras Theorem,

Base = √h^2 - p^2 = √4^2 - 3^2 = √16 - 9 = √7.

so,

CosA = b/h = √7 / 4 units.

CotA = b/p = √7 / 3 units.
