Step-by-step explanation:

Given : sin theta = 3/ 5

cos theta = 4/ 5

sin2theta = 2sin theta cos theta

cos 2 theta = 2 cos square theta - 1

sin2 theta = 2 × 3/5 × 4/ 5

= 24/ 25

cos 2 theta = 2 (4/5)^2 - 1

= 2(16/25) - 1

= 32/25 - 1

= 7/ 25

Final answer = 24/25 + 7/ 25

= 31/ 25

= 1.24

Hope this answer helps
