Answer:
x = 13
Step-by-step explanation:
Note that the side length x is opposite of the right angle, which means that it is the hypotenuse, which will usually be denoted as c.
Set the equation:
a² + b² = c²
let:
a = 5
b = 12
c = x
Plug in the corresponding numbers (& x) to the corresponding variables:
(5)² + (12)² = (x)²
Simplify. First, solve for the power, and then add:
x² = (5²) + (12²)
x² = (5 * 5) + (12 * 12)
x² = 25 + 144
x² = 169
Next, root both sides of the equation:
√x² = √169
x = √169 = √(13 * 13) = 13
x = 13

Note the rules, and it should be easier:
30-60-90° = 1 , √3 , 2
45-45-90° = 1 , 1 , √2
Any other measurements use the equation: a² + b² = c²
Answer:
Step-by-step explanation:
As 4 is accumulated by thousands place
And ones place is 4 into 2/twice
And hundreds place accumulates zero
And tens place is 4 - 0=4
The no is
4048
Irrational, because if you simplify the root V72=6V2

Answer:</h2>
Since both angles are vertical angles, we need to set them equal to each other.
The final answer is <em>x = 10</em>.
