Answer: x = 2
Step-by-step explanation:
![10x - 15x + 5= -45 + 40](https://tex.z-dn.net/?f=10x%20-%2015x%20%2B%205%3D%20-45%20%2B%2040)
subtract 5
![10x - 15x= -45 + 40-5](https://tex.z-dn.net/?f=10x%20-%2015x%3D%20-45%20%2B%2040-5)
Combine like terms;
![-5x=-10](https://tex.z-dn.net/?f=-5x%3D-10)
Divide by -5
![x=\frac{-10}{-5}\\ x=2](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B-10%7D%7B-5%7D%5C%5C%20x%3D2)

Answer:
140 degrees
Step-by-step explanation:
180-20+20 =140
As they are similar figures,we can use the ratio of the side to find out the value of z.
The only side that both have the value indicated is 4 and 6,therefore we would use it to find the ratio.
The eqaution would be:
6/4 = z/8
3/2 = z/8
3×8 = 2z
z = 24/2
z = 12
Thus the value of z is 12.
Hope it helps!
