Question

if sin theta is equals to 3 by 5 and Cos teta is equals to 4 / 5 find the value of sin square teta + cos square teta.​

Answer 1

Answer:

1

Step-by-step explanation:

sin square theta + cos square theta

9/25 + 16/25 = 1

Answer 2

Answer:

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
