Add and turn to simplest form.

The answer is

Step-by-step explanation:

First of all we must make sure that the surds have equal roots

For 5√490

For 4√40

So we have

Using the rules of surds simplify the expression

That's

So we have

We have the final answer as

Hope this helps you

ian gonna lie that is way to much

proofs involving isosceles triangles often require special consideration because an isosceles triangle has several distinct properties that do not apply to normal triangles.(more about triangle types) therefore, when you are trying to prove that two triangles are congruent, and one or both triangles, are isosceles you have a few theorems that you can use to make your life easier.

step-by-step explanation:

an isosceles triangle has two congruent sides and two congruent angles. the congruent angles are called the base angles and the other angle is known as the vertex angle. ∠bac and ∠bca are the base angles of the triangle picture on the left. the vertex angle is ∠abc
