Simplify: √(5 + 2√6).

Given that,

We can rewrite it as,

So,

We know that,

Here, a = √2 and b=√3.

So,

So, the square root and the square get cancelled. So,

Therefore,

Step-by-step explanation:

−

We can rewrite it as,

⟼2+3+2(2)(3)

So,

We know that,

a^2+b^2+2ab=(a+b)^2⇛a2+b2+2ab=(a+b)2

Here, a = √2 and b=√3.

So,

So, the square root and the square get cancelled. So,

Therefore,

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth
