$(a\sin(\theta) - b\cos(\theta))^2\\= a^2\sin^2(\theta) - 2ab\sin(\theta)\cos(\theta) + b^2\cos^2(\theta)\\= a^2\sin^2(\theta) - ab\sin(2\theta) + b^2\cos^2(\theta)$

Rodney is given two linear equations: x – y = 11 and 2x + y = 19. What value of x should he get as a solution for this system of

antiseptic1488 [7]

The solution to the answer is as follows:

<span>x - y = 1...[1],

2x + y = 19...[2], {[1]+[2]}---> 3x = 30,

ie., x = 10. C is correct answer.
</span>
I hope my answer has come to your help. God bless and have a nice day ahead!
