Answer:

x = 46°

Step-by-step explanation:

The sum of interior angles = (n-2) × 180°

= (5-2) × 180°

= 540°

2x+3x+3x-4+3x+x-8 = 540°

12x = 552°

x = 46°

PLEASEEE HELP ! I WOULD APPRECIATE IT VERY MUCH :)
azamat

hi!

so the original equation is (x^2 -121) / x+ 11.

Those two equations look similar...

well, we know that the top equation looks like a^2 - b^2, and that equation iis equivalent to this equation: (a+b)(a-b).

So if we factor that out, we get:

( (x + 11) * (x-11) )/ (x + 11)

we can cancel the x+11 on the top and the x+11 on the bottom out.

that leaves us with x-11.

Hope this helped!

What is the average of -2.6, 1.8, -3.3, -2.7, 2.2 ?<br> I dont understand this.
olya-2409 [2.1K]
Average = Mean

To find the mean, add up the numbers and divide it by how many numbers there are.

So,  -2.6+1.8+(-3.3)+(-2.7)+2.2=-4.6

There are 5 numbers in total.

-4.6 \div 5=-0.92

To do these types of division, ignore the decimal and add a 0 at the end.

So we can do:
-460\div5=-92

And put back the decimal.
Hope this helps :)

This is just a basic proportion. 5/8 = x/12. So the 5 foot tall women would have a 7.5 foot shadow.
