How do I find the length of the side.

ludmilkaskok [199]

Use the Pythagorean theorem /look at the picture/

? = x

$1.\\x^2+13^2=28^2\\x^2+169=784\ \ \ |subtract\ 169\ from\ both\ sides\\x^2=615\\\boxed{x=\sqrt{615}}\\\\3.\\x^2+10^2=28^2\\x^2+100=784\ \ \ \ |subtract\ 100\ from\ both\ sides\\x^2=684\\x=\sqrt{684}\\x=\sqrt{36\cdot19}\\x=\sqrt{36}\cdot\sqrt{19}\\\boxed{x=6\sqrt{19}}$

A printer takes 30 minutes to print a banner and a poster. I will take 50 minutes to print a banner and three posters. How long

qwelly [4]

Answer:

It takes the printer 20 minutes to print a banner

Step-by-step explanation:

Notice that there are two unknowns in this problem: the time to print a poster and the time to print a banner. Let's assign the letter "b" to the time it takes to print a banner, and "p' the time it takes to print a poster.

So we can write the following two equations involving the total amount of time that takes to print in the two cases:

$b+p=30\\b+3p=50$

We can solve for the unknown "p" by subtracting term by term in the equation set above:

$b+3p=50\\b+p=30\\\\b-b+3p-p=50-30\\2p=20\\p=10$

So it takes 10 minutes to print each poster, we can find the time it takes to print the banner by using the value we just found in one of the equations:

$b+p=30\\b+10=30\\b=20$

So, it takes 20 minutes to print a banner.
