Verified Answer

2costheta sintheta=1. Then 7cos theta 6sinthera=?

Multiply 6 in first equation i.e 2costheta+sintheta=1 .

We get 12costheta +6sintheta=6

Now let, 7costheta+6sintheta=K

Eliminate sintheta , and get values of sintheta and costheta in terms of K

Sintheta=2K-7/5 , costheta=6-K/5

NOW we know sinsqauretheta +cossquaretheta=1 .put values here in terms of K and then a quadratic equation in K will form , on solving it we get K=6 or 2.hence prooved
