Answer 1

Answer:

3/4

Step-by-step explanation:

we know Sin theta= perpendicular / hypotaneous

here sin theta is 3/5 so in a right angle triangle of perpendicular 3 and hypotenuse 5 the base length will be 4 (Pythagoras theorem)

now we know tan theta is perpendicular/base

so from above result it will come to 3/4

Answer 2

Answer:

sin tetha= 3/5 = opposite side / hypotenuse

hypotenuse square = side square + side square

5 square = 3 square + side square

root over 5 square - 3 square = side

side = 4

Now cos tetha = adjacent side / hypotenuse

cos tetha = 4/5

tan tetha = opposite side / adjacent side

Tan tetha = 3/4
