Answer: You add up all the terms given of EACH angle, and make this an addition problem that is "equal to 180" ; since all triangles have three angles that add up to 180 degrees. Then you solve for "x".
__________________________________________________
(as follows) ; to get: " x = 29 ⅔ ° " .
_______________________________________
3x + 4 + 2x + x + 8 = 180 ;
_______________________________________
Combine the "like terms" ;
3x + 2x + x = 6x ;
4 + 8 = 12
So, we have: 6x + 12 = 180 ;
Now, subtract "12" from each side of the equation:
__________________________________________
6x + 12 − 12 = 180 <span>− 12 ;
</span>__________________________________________
to get:
6x = 178 ;
Now, divide EACH SIDE of the equation by "6" ; to isolate "x" on one side of the equation; and to solve for "x" ;
______________________________________
6x / 6 = 178 / 6 ;
to get: x = 178/6 = 29 ⅔ ° .
______________________________________
x = 29 ⅔ ° .

Yes, it is possible to construct a regular hexagon with a straight edge and compass I did it in my geometry class.
Answer:
2 inches
Step-by-step explanation:
A square is basically two triangles put together and since a square has four right angles you can use the Pythagorean Theorem to do this.
A squared +b squared <24
5 squared x 5 squared = 25
Sooooooo...... ;)
Get it?
Answer:
37.7
Step-by-step explanation:
First, we have to divde 22/7 to find the scale factor. I chose 22 and 7 because those two sides are ocngruent. We get 3.14. We then have to multiply 12 by 3.14 beacuse that is the side that is congruent with the side y. When you multiply you should get 37.68. Since we have to round we get 37.7.
