Answer:
5
Step-by-step explanation:
a=12 (height)
c=13 (hypotenous)
b=? (base)
By using Pythagoras theorm
We have, hypotenous sq=base sq+height sq
Let b =base SO, base sq=hypotenous Sq-height Sq
=>base Sq =13sq-12sq
Base Sq =169-144
Base Sq =25
Base =5 (shifting the sq)....

<h2>1,366</h2>
Step-by-step explanation:
P - parenthsis
E - exponents
M - multiplication
D - division
A - addition
S - subtraction
<h3>STICK TO THE ORDER:</h3>
7 + 5 x (6 x 45) + 9 = 1,336 ( Not the pemdas order)
But,
<h3>7 + (5 x 6)45 + 9 = 1,366 is the correct order for using PEMDAS.</h3>
I'm not sure if this is the easiest way of doing this, but it surely work.
Let the base of the triangle be AB, and let CH be the height. Just for reference, we have

Moreover, let CH=y and BC=z
Now, AHC, CHB and ABC are all right triangles. If we write the pythagorean theorem for each of them, we have the following system

If we solve the first two equations for y squared, we have

And we can deduce

So that the third equation becomes

(we can't accept the negative root because negative lengths make no sense)
Answer:

Step-by-step explanation:
To express a proper fraction in decimal form.
Divide the numerator by the denominator, that is
22 ÷ 7 ≈ 3.1429 ( to 4 decimal places )
Answer:
i4=1
Step-by-step explanation:
Explanation: Rewrite i14 as (i4)3×i2 . If i=√−1, then i2=−1 . From here (i2)2=(−1)2 , so i4=1
