Question

given 15Cot A=8, find Sin A,cos A and Cot A​

Answer 1

Answer:

cosA=8,sinA=15

Step-by-step explanation:

15cotA= 8

cotA=8/15

cosA/sinA=8/15

cosA=8

sinA=15.

Thanks!

Answer 2

Answer:

sinA=15/17,cosA=8/17,cotA=8/15

Step-by-step explanation:

Given:15 CotA=8

CotA=8/15

CotA=Adjacent side/Opposite side=8/15

As per pythagoras theorem:

(Hypotenuse)^2=Opposite^2+Adjacent^2

Hypotenuse^2=(15)^2+(8)^2

Hypotenuse^2=225+64

Hypotenuse^2=289

Hypotenuse=root 289

Hypotenuse=17

SinA=Opposite/Hypotenuse

SinA=15/17

CosA=Adjacent/Hypotenuse

CosA=8/17

CotA=8/15

CosecA=17/15=Hypotenuse/Opposite

SecA=17/8=Hypotenuse/Adjacent

TanA=15/8=Opposiye/Adjacent
