2 Points
Which methods could you use to calculate the x-coordinate of the midpoint of
a horizontal line segment with endpoints at (0,0) and (20, 0)?
Check all that apply.
A. Divide 20 by 2
B. Count by hand
c. Divide O by 20
D. Divide 20 by 0

to get coordinate of mid point use (20+0)/2 for x coordinate,

A is correct answer!

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

answer: 8d

step-by-step explanation:

45+5= 50+5=55+5=60
