Answer:

AB = 25

Step-by-step explanation:

First things first, we know that these triangles are similar. Now let's find BC using the Pythagorean Theorem. BC = 5\sqrt5, this side is similar to the 5 side of the smaller triangle. That means each side of the larger triangle \sqrt5 times larger than the corresponding side on the small triangle. That means AB is \sqrt5 times larger than BC as well. So multiply BC by \sqrt5 get us the answer.

a=6, b=2

Step-by-step explanation:

Use simplification into substitution
\frac{a}{3} =1+\frac{2}{b}

a=3(1+\frac{2}{b})

a=3+\frac{6}{b}

We can now plug this value of <em>a</em> into the second equation.

\frac{3+\frac{6}{b} }{4} +\frac{3}{b} =3

Get rid of fractions in the numerators and/or denominators

\frac{3b+6}{4b} +\frac{3}{b} =3

Then we can match the denominators

\frac{3b+6}{4b} +\frac{12}{4b} =3

Combine

\frac{3b+18}{4b} =3

Divide both sides by three

\frac{b+6}{4b} =1

Get rid of fractions

b+6=4b

Single out <em>b</em>

6=3b

b=2

Now we can plug it into the equation

\frac{a}{3} -\frac{2}{2} =1

\frac{a}{3} =2

a=6

Now we can check it;

\frac{6}{3} -\frac{2}{2} =1

↑CORRECT

\frac{6}{4} +\frac{3}{2} =3

↑CORRECT
