Answer:
Assuming the similarity is that BC scales to EF, answer is
D. 1.5BC
Step-by-step explanation:
Because the triangles are smilar, AB/BC = DE/EF
If AB = 2BC
then DE = 2EF
but also DE = 3BC
so 2EF = 3BC
EF = 1.5BC
we know that
The sum of all interior angles in the polygon is equal to the formula
![(n-2)*180\°](https://tex.z-dn.net/?f=%28n-2%29%2A180%5C%C2%B0)
where
n is the number of sides of the polygon
In this problem we have
![n=6](https://tex.z-dn.net/?f=n%3D6)
substitute the value in the formula
![(6-2)*180\°=720\°](https://tex.z-dn.net/?f=%286-2%29%2A180%5C%C2%B0%3D720%5C%C2%B0)
<u>Find the value of x</u>
![720\°=x\°+108\°+113\°+132\°+75\°+160\°\\720\°=x\°+588\°\\x\°=720\°-588\°\\x=132\°](https://tex.z-dn.net/?f=720%5C%C2%B0%3Dx%5C%C2%B0%2B108%5C%C2%B0%2B113%5C%C2%B0%2B132%5C%C2%B0%2B75%5C%C2%B0%2B160%5C%C2%B0%5C%5C720%5C%C2%B0%3Dx%5C%C2%B0%2B588%5C%C2%B0%5C%5Cx%5C%C2%B0%3D720%5C%C2%B0-588%5C%C2%B0%5C%5Cx%3D132%5C%C2%B0)
therefore
<u>the answer is</u>
the measure of x is ![132\°](https://tex.z-dn.net/?f=132%5C%C2%B0)
Answer:
-4e - 9
Step-by-step explanation:
This requires combining like terms, which means that you combine the same types of values. In this one there are two "types" of values: something that involves the variable e and just normal numbers. Let's say that the "e"s are oranges and the regular numbers are apples. Remember, you can't simply add oranges and apples together
let's start with apples (the regular numbers)
you have -19 (just pretend the minus sign is attached to the value following)
and +10
so -19+10 is -9
we have -9 apples
so now let's look at oranges, represented by e
you have 3e and -7e
if one e is one orange, then you could say that there are 3 oranges and -7 oranges
so if you subtract you get -4e, or -4 oranges
now let's add that back together with the apples, remembering that you can't actually combine them
so it would be -4e - 9
(-4 oranges and -9 apples)
