Question

If sin theta=3/5 find the value of sin2theta +cos2 theta

Answer 1

Answer:

1

Step-by-step explanation:

Given,. Sin(theta)=3 by 5 (P/H) Then,we have. B=√H2-P2 (root square of H and minus Square of P). B=√sqare of 5- square of 3. B=√25-9. B=√16. B=4. Now, according to the question. we have,. Cos(theta)=B/H. so,Cos(theta)=4/5. then, (3/5)2+(4/5)2. =9/25+16/25 =9+16/25 =25/25. =1. Hence,the value of sin2 theta+ Cos2 theta=1. I hope you are understand.plz marks the above ans.in brainlist .
