Question

sin²theta = 0.25. find cos theta and tan theta​

Answer 1

Step-by-step explanation:

sin^2A = .25

= 25/100

sinA = 5/10 = L/K

BY PYTHAGORAS THEOREM

K^2= L^2+A^2

A= (K^2-L^2)^1/2

A= (75)^1/2

cosA =A/K

=(75)^1/2 /10

tanA = L/A

= 5/(75)^1/2

Answer 2

Step-by-step explanation:

sin^2A = .25

= 25/100

sinA = 5/10 = L/K

BY PYTHAGORAS THEOREM

K^2= L^2+A^2

A= (K^2-L^2)^1/2

A= (75)^1/2

cosA =A/K

=(75)^1/2 /10

tanA = L/A

= 5/(75)^1/2
