Question

if sin theta =3/5 and cos theta =4/5 find the value of sin²theta+cos²theta​

Answer 1

Answer:

1

Step-by-step explanation:

sintheta = 3/5

= > sin² theta = 9/25

and cos theta = 4/5

=> cos² theta = 16\25

so, sin ² theta + cos² theta = 9/25 + 16/25

= 25/25

= 1

Answer 2

Answer:

Answer is 1

(3/5)^2 + (4/5)^2 = 9/25 + 16/25 = 25/25 = 1
