If a= 2ft and c= 11ft. Find the missing side of the right triangle

Mathematics
1 answer:
dlinn [17]2 years ago

Answer:

\sqrt{117} or 3\sqrt{13}

Step-by-step explanation:

The formula for finding the any side of the triangle is

a^{2}+b^{2} =c^{2}

We know that a=2 and c=11, so we can go ahead and plug those into the formula.

2^{2}+b^{2} =11^{2}

4+b^{2} =121

To find side b, we have to make it alone on one side. Subtract 4 on both side.

b^{2} =117

Now square root both sides, and that leaves us with:

b=\sqrt{117} or 3\sqrt{13}

Tannin and Dax bought a new video game for $48 to use the coupon for 25% off how much would the game cost if they paid full pric
olchik [2.2K]

Answer:

$64

Step-by-step explanation:

After using a 25% discount coupon, they paid 48 for the video game.

It means, <em>which number, decreased by 25%, would give us 48?</em>

<em />

First, 25% to decimal is:

25/100 = 0.25

Now, if we let the original price be "x", we can say:

x decreased by 0.25 of x would give us 48

Translating this to algebraic equation gives us:

x - 0.25x = 48

Now, we solve this:

x - 0.25x = 48\\0.75x=48\\x=\frac{48}{0.75}\\x=64

If they paid full price, the video game would cost $64
