Given 15 cot a=8 Find sin A and sec A | Trigonometry

Exercise 8.1 class 10
Given 15 cot a = 8
Find sin A and sec A

Remember📋:
cot a = base/perpendicular
or
cot a = b/p

Base is the side adjacent to given angle
Perpendicular is the side opposite to given angle

Hint 💡:
Transpose 15 to RHS
cot a = 8/15

sin a = perpendicular/hypotenuse
sec a = hypotenuse / base

Practice:
In fig 8.13 find tan P - cot R

Mam will it be
15 cotA=8
Cot A=15 /8 or it will be reciprocal to 8/15

Thank you mam
If costheeta=0.6 show that 5 sin theeta-3 tan theeta=0
This question is very difficult for me mam
Please explain mam
