Question

Given Line Segment CD as shown with Line Segment CA~=(That is a congruent symbol)Line Segment BD and CD=98. If CB=3(x+8) and AD=4(x+3), find AB

Answer 1

Answer 2

let's call AB, y

so you can set up an equation
CB + AD - AB = CD
(you subtract AB because it is counted twice )

Answer 3

The answers could be 12, 22, 36, 10, 42, 18, 6, 8, 30, 2, or 124

Answer 4

so

3(x+8) +4(x+3) -y =98

Answer 5

I tried that and kept getting 99 instead, but when I put 1 as the y It came to be 0 putting it back in

Answer 6

did you solve for x first?

Answer 7

since CA is congruent to BD, you can set this up

3(x+8) = 4(x+3)
what did you get for x?

Answer 8

x=5

Answer 9

maybe check again? i got 12

Answer 10

that is what I meant I hit 5 instead

Answer 11

ok. cool

now plug this into the equation i set in the beginning and solve for y

Answer 12

y=22

Answer 13

yes. 22 is coreect

Answer 14

thanks
