If alpha and beta are the angles in the first quadrant tan alpha = 1/7 and sin beta =1/ root 10 then usind the formula sin (A +B) = sin A. CosB + sina. CosB find the value of alpha + 2beta

Step-by-step explanation:

Using Pythagorean Identities:

The sum Identity is:

I will just follow what the question asks.

Now we can perform the sum identity:

But we are not done yet! You want

and not

You actually want the
