Answer 1

Answer:

cotA=4/3

sinA=3/5

this is your answer ❣️❣️✌️ ✌️

Answer 2

SOLUTION:-

Given:

3cotA= 4

=) cotA= 4/3

We know that,

$cot A = \frac{B}{P} = \frac{4}{3}$

Using Pythagoras Theorem;

H² = P² + B²

H² = 3² + 4²

H² = 9 + 16

H² = 25

H= √25

H= 5

Now,

sinA= P/H

=) 3/5

Hope it helps ☺️
