A right triangle has legs with the lengths of 2 and 5, find the length of the hypotenuse

Volgvan

Answer:

$\sqrt{29}\ units$

Step-by-step explanation:

we know that

In a right triangle

Applying the Pythagorean Theorem

$c^2=a^2+b^2$

where

c is the hypotenuse (the greater side)

a and b are the legs (perpendicular sides)

In this problem we have

$a=2\ units\\b=5\ units$

substitute

$c^2=2^2+5^2$

$c^2=29$

$c=\sqrt{29}\ units$

Lenny is competing with his cousin, Jasper, in an indoor rock-climbing contest. At the start of the climb, Lenny makes his way 5

Answer:

$4\frac{1}{2}$ feet further.

Step-by-step explanation:

Since these are mixed numbers that are both in fourths, we can easily subtract the two numbers. However, I find it easier if we first convert both mixed numbers into improper fractions.

$5\frac{1}{4} = \frac{5\cdot4+1}{4} = \frac{21}{4}$

$9\frac{3}{4} = \frac{9\cdot4+3}{4} = \frac{39}{4}$

Now we can subtract the numerators:

$\frac{39}{4} - \frac{21}{4} = \frac{39-21}{4} = \frac{18}{4}$

$\frac{18}{4}$ simplifies down to $\frac{9}{2}$ .

Converting $\frac{9}{2}$ to a mixed number is easy - 2 goes into 9 4 times (8) with one remainder so:

$4\frac{1}{2}$ .

Hope this helped!
