Find the value of X in that isosceles triangle shown below
ipn [44]

Answer:

sqrt(13) =x

Step-by-step explanation:

We have 2 right triangles, one on the right and one on the left

The base is 1/2 of 4 or 2 and the height is 3

We can use the Pythagorean theorem to find the hypotenuse

a^2 + b^2 = c^2

2^2 + 3^2 = x^2

4+9 = x^2

13 = x^2

Take the square root of each side

sqrt(13) =x

What is 9 1/10 - 4 3/4
Nady [450]

Answer:

\frac{87}{20}

Step-by-step explanation:

First we need to change the mixed numbers into improper fractions.

9 x 10 = 90 + 1 = 91/10

4 x 4 = 16 + 3 = 19/4

Now we need to get them into simplest terms. There is a few ways to do this, but I know that 10 x 2 = 20 and 4 x 5 = 20 so I will use 20.

\frac{91}{10} = \frac{91 x 2}{10 x 2} = \frac{182}{20}

\frac{19}{4} = \frac{19 x 5}{4 x 5} = \frac{95}{20}

Now we can subtract:

\frac{182}{20} - \frac{95}{20} = \frac{87}{20}

And that leaves us with our answer :D
