1. An expression is shown below. V21x
For which value of x should the expression be
further simplified?
A. 5
B. 6
C. 11
D. 55

we have that√(87*x)we know that87 is equal to> 3*29In order for the square root to go further, the number for "x" has to have a factor of 3 or 29the number 21> 3*7so√(87*x)> √(3*29*3*7)> √(3²*29*7)> 3√203the answer isx=21

Step-by-step explanation:

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
