Consider the figure.
find ab if bc = 4, bd = 5, and ad = 5

so I think it's a rectangle. and AB is the diagnal line. to find AB, we need to use the hypothegorin teorin.

BD=5, DA=5

let x represent the AB

formula= a²+b²=c²

= 5²+5²= x²

= 25+25=x²

=50=x²

=square root of 50= 7.07

AB is 7.07

∠cbe and ∠deb are same-side interior angles.

i took the test

answer: 80,000

step-by-step explanation:

the population doubles every day.

10,000*2=20,000 day 4

20,000*2=40,000 day 5

40,000*2=80,000 day 6
