1. Write a two-column proof. Given: Triangle ACD is isosceles; <1 is congruent to <3

Prove: Segment AB || Segment CD

Check it below, please

Step-by-step explanation:

Hi there!

Let's prove segment AB is perpendicular to CD. Attention to the fact that a two column proof has to be concise. So all the comments can't be exhaustive, but as short as possible.

Let's recap: An isosceles triangle is one triangle with at least 2 congruent angles.

Statement                     Reason

                    Given

       Isosceles Triangle the altitude, the bisector coincide.          

              Bisector equally divide a line segment into two congruent      

Right angles, perpendicular lines.                  

                   Perpendicular Line segment      

the answer is f(x)=2x-1

step-by-step explanation:

7 weeks

step-by-step explanation:

convert each fraction to the least common multiple of 20, so 3/4 = 15/20 & 1/10 = 2/20, then divide 15 by 2 and you get a little over 7, so the food will last 7 weeks.
