For this case by similarity of triangles we can use the following relationship:
(x) / (9) = (5) / (15)
We clear the value of x:
x = ((5) / (15)) * (9)
Rewriting:
x = (1/3) * (9)
x = 3
Answer:
The value of x for this case is:
x = 3
<span>The answer is B) 160
First find exterior angle
360 / 18 = 20
Interior angle = 180 - 20 = 160

Answer:
The answer is C
Step-by-step explanation:
Answer:
-4n - 5
Step-by-step explanation:
4 - 9
= -5
-5n + n
Combine like terms
= -4n
-4n - 5
A 5 is best predicted number
