Question

if sin theta = 3/5 then find the value of cos theta and ten theeta​

Answer 1

Answer:

Step-by-step explanation:

sin theta= 3/5

opposite/hypotenuse= 3/5

substitute in right angle triangle

by pythagoras theorem

ac^2= ab^2+bc^2

5^2= 3^2 + x^2

25= 9+ x^2

x^2= 25-9

x^2= 16

x= 4

cos theta= adjacent/hypotenuse

              = 4/5

tan theta= opposite/adjacent

              = 3/4
