Step-by-step explanation:
We're going to be evaluating if we can round 2. (Values in the 10's place)
The value in the 'ones' place has to be greater than or equal to 5 in order to round up 2.
Since 8 is greater than 5, we can round up 2.
<u>Rounded answer:</u>
38830

Answer:
5.5 7
Step-by-step explanation:
Answer:
9
Step-by-step explanation:
We can set up a systems of equations to find the value of the third side.
Let's assume that 
is the length of both sides 1 and 2. Let's also assume that 
is the length of the third side.
We know that 
, and looking at the first clue we can make the equation 
.
We can substitute y into the equation .
So the length of the side that is the same as the second is 7.
Now we can plug this into the equation to find .
Hope this helped!
Answer:
x=13 degrees
Step-by-step explanation:
First, think of the remote interior angle theorem. So basically the remote interior angles that don't share a vertex with the exterior angle is the sum of the exterior angle. So that means ∠EBC+∠BEC=∠ECD. ∠ECD=64 degrees+90 degrees=154 degrees. ∠EBC is equal to 180 degrees minus 3x because line AD is a line so ∠ABE and ∠EBC are supplementary angles so basically they add up to 180 degrees. So the equation is (180-3x)+x=154. Simplify the equation and you should get x=13 degrees:)
