Trigonometric ratios in a right triangle :-

① sin A ➙ Perpendicular/Hypotenuse

➙ BC/AC

② cos A ➙ Base/Hypotenuse

➙ AB/AC

③ tan A ➙ Perpendicular/Base

➙ BC/AB

④ cosec A ➙ Hypotenuse/Perpendicular

➙ AC/BC

⑤ sec A ➙ Hypotenuse/Base

➙ AC/AB

⑥ cot A ➙ Base/Perpendicular

➙ AB/BC

Answer 2

Answer:

Refer to the attachment ........☺

And.....

following standard ratios:

following standard ratios:

sinθ =opposite / hypotenuse,

cosθ =adjacent / hypotenuse,

tanθ =opposite / adjacent.

Allied to these are the three reciprocal ratios, cosecant, secant and cotangent:

cosecθ=hypotenuse / opposite,

secθ=hypotenuse / adjacent,

cotθ=adjacent / opposite.

These are called the reciprocal ratios as

cosecθ=1sinθ,

secθ=1cosθ,

cotθ=1tanθ.
