Answer:
AB = 2
Step-by-step explanation:
Using the secant- secant theorem, that is
PA × PB = PD × PC , substitute values
10(10 + AB) = 8(8 + 7)
100 + 10AB = 8 × 15 = 120 ( subtract 100 from both sides )
10AB = 20 ( divide both sides by 10 )
AB = 2
Area= width * length
w=1/2 length
Area+ 128 sqr ft
Plug in the information you know into the Area formula.
128 ft2= w * l
128 ft2= (1/2 l)(l)
128 ft2=l/2
multiply both sides by 2 to get rid of the fraction
256 ft2 = l
take the square root of 256
16=length in feet
1/2length = width = 8 feet
Hope this helps! :)
It says Sandeep has twice as much as Sonia. Thus, let Sandeep's amount be 2x and Sonia's amount be x.
Now, together they have 150.
Thus, the equation;
x+2x=150
Now let's solve the equation;
3x=150
x=150/3
x=50
Thus, Sonia has 50
