Given sin A = 3/5.
We know that cos^2 theta = 1 - sin^2 theta
cos theta = root 1 - sin^2 theta
cos A = root 1 - sin^2 A
= root 1 - (3/5)
= root 1 - 9/25
= root 16/25
= 4/5. --------- (1)
We know that Tan theta = sin theta/cos theta
Tan A = sin A/cos A
= 3/5/4/5
= 3 * 5/5 * 4
= 15/20
= 3/5. ----- (2).
From (1) and (2), we get
Cos A + Tan A = (4/5) + (3/5)
= 4 + 3/5
= 7/5.
Hope this helps!

Answer:
Step-by-step explanation:sina=3/5
Cosa=root 1-sin square a =1-9/25=16/25=4/5 tana=sina/cosa=3/5×5/4=3/4 cosa+tana=4/5+3/4=31/20
