ABCD is a rectangle. Find the length of each diagonal. AC = 2(5a + 1) and BD = 2(a + 1) I kept getting 0 and 2 but Im not sure if that right
come back please i like help you but just than collaborate - ok. ?
do you know how are the diagonales of a rectangle ? has different length ? or are equales ?
Hello!!! ANd thank you Sorry thats all the info they give me for this equation
yes these are eligible to solve this exercise just you need to know how are the length of diagonals of a rectangle ? |dw:1464390488741:dw|
how you see there on my posted image how are these length of diagonales ? are differents ? or equales ?
do you know how many degree has every angle of a rectangle ?
angles - sorry so has 90 degree what mean that are congruent so equales - yes ?
courage
so what is your opinion please ?
I believe they are equales. and also AB and CD are parallels too
so this is true really that AC = DB so from these given datets than you rewrite this equalitie can you solve it for ,,a" ? how many value wil get for a ?
so you know that AC = BD and you know bc. given that AC = 2(5a +1) and BD = 2(a+1) yes ?
Yes So A = 0???
can you writing here please your calculi how you get a=0 ?
how you get above wrote zero for a ?
Okay Hold up please. 2(5a+1)=2(a+1) 5a+1=a+1 4a=0 (Then that's were I got losted, Sorry)
exactly this is right,correct wrote and from there result that a=0 yes ?
Yes
so now that you know the value of ,,a" so you can calculi easy the length of diagonales easy
without this easy from the end - sorry
how you calculi these length of AC and BD ?
so you know now that a=0 and you know that AC = 2(5a +1) and BD = 2(a+1) than what you need to do for get these length ?
You have to plug the A value back into the equation???
just substitute this value of a in place of a inside this equations and will get the right length value sure
yes exactly
so in this case AC = ?
2!?
Thank you so much!!!
21 ? really you get 21 ? how please ? can you rewriting these your calculi how you get this 21 ?
I mean 2
ohhh sorry AC =2 is right so than BD = ?
Also 2
exactly - nice so do you understand it now sure clearly ?
Yes I do. Thank you. That really helped
anytime with great pleasure just tag me bye bye
