Answer:
x = 2
Step-by-step explanation:
First, let's write out our equation:

I want to isolate x on one side, so first, I'll add 4 to both sides to remove the -4 from next to 2x:

Notice that I combined like terms with the -4 and 4 (to get 0) and the 6 and 4 on the right side (to get 10). Next, I'll add 3x to both sides:

And then I'll add like terms:

Now, all we have to do is divide both sides by 5:

And there's our answer. Hopefully that's helpful! :)
Answer:
AC=15
BC=17
AB=?
According to Pythagore's Theorem: AB² + AC² = BC².
AB² = BC² - AC²
= (17)² - (15)²
= 289 - 225
AB² = 64
AB = √(64)
= 8.
So AB = 8.
Answer:
No
Step-by-step explanation:
In both exterior and interior angles on the same side of the transversal, one of the angles will be acute and the other one will be obtuse making them different. Therefore, there is no relationship between them.
