Answer:

$\frac{2191919}{1000000}$

Step-by-step explanation:

To write 2.191919 as a fraction you have to write 2.191919 as numerator and put 1 as the denominator.

Now you multiply numerator and denominator by 10 as long as you get in numerator the whole number.

2.191919 = $\frac{2.191919}{1}$

$\frac{2.191919}{1}$ = $\frac{21.91919}{10}$

$\frac{21.91919}{10}$ = $\frac{219.1919}{100}$

$\frac{219.1919}{100}$ = $\frac{2191.919}{1000}$

$\frac{2191.919}{1000}$ = $\frac{21919.19}{10000}$

$\frac{21919.19}{10000}$ = $\frac{219191.9}{100000}$

$\frac{219191.9}{100000}$ = $\frac{2191919}{1000000}$

The measure of first angle is 34 degrees and measure of second angle is 56 degrees

Solution:

Given that, the exterior sides of two adjacent angles make a right angle

Therefore, these adjacent angles forms 90 degrees

Let the second angle be "x"

The first angle has a measure that is six more than half the second

Therefore,

first angle = 6 + half of "x"

$\text{ first angle } = 6 + \frac{x}{2}$

Since these two angles forms 90 degrees,

first angle + second angle = 90

$x + 6 + \frac{x}{2} = 90\\\\\frac{2x + 12 + x}{2} = 90\\\\2x + 12+x = 180\\\\3x + 12 = 180\\\\3x = 180 - 12\\\\3x = 168\\\\x = 56$

Therefore, first angle is:

$\rightarrow 6 + \frac{56}{2} = 6 + 28 = 34$

Thus measure of first angle is 34 degrees and measure of second angle is 56 degrees

Step-by-step explanation:

d = √(x2 - x1)^2 + (y2 - y1)^2 + (z2 - z1)^2

P1(0, 0, 0) P2(-6, 8, 3)

Substitute the values in the above equation and you will get

d = √(-6 - 0)^2 + (8 - 0)^2 + (3 - 0)^2

= √(36 + 64 + 9)

= √109

= 10.44
