Answer:
36
Step-by-step explanation:
Using the angle addition postulate
angle 1+angle 2+angle 3=180
Angle 2 is 90 degrees,
Angle 1 is 2x degrees
Angle 3 is 3x degrees
Plug this into equation
![2x + 90 + 3x = 180](https://tex.z-dn.net/?f=2x%20%2B%2090%20%2B%20%203x%20%3D%20180)
![5x + 90 = 180](https://tex.z-dn.net/?f=5x%20%2B%2090%20%3D%20180)
![5x = 90](https://tex.z-dn.net/?f=5x%20%3D%2090)
![x = 18](https://tex.z-dn.net/?f=x%20%3D%2018)
Plug 18 into 2x
![2(18) = 36](https://tex.z-dn.net/?f=2%2818%29%20%3D%2036)
If all angles are right angles then they are 90°
If x is equal to -3 then 2X +7 is equal to one
IfN squared is equal to 81 then N is equal to nine
If tourist are in Texas then the are at the Alamo
It would be (rounded) 5
Because
31 / 6.15 = 5.04065
Hope this helped
Have a great day/night
