Question

if sin teta +Cos Teta= 7/5 what is sin teta×cos teta?​

Answer 1

Answer:

Step-by-step explanation:

squaring both sides

sin^2theta+cos^2theta+2sinthetacostheta=49/25  

1+2sinthetacostheta= 49/25 (as sin^2theta+cos^2theta=1)

sinthetacostheta= (49/25-1)/2

=12/25

Answer 2

Answer:

Sin A= 3/5

Cos A = 4/5

Step-by-step explanation:
