ABD is the supplement of DBC, so it is equal to 180-130= 50 degrees.

If BE is the bisector, then it splits the angle in half evenly. 50/2=25 degrees for EBA and DBE each.

Final 25 degrees

Answer from: 19mcgough

Becuase this is a straight angle, we know that the total amount of the degrees adds up to 180. We can write an equation to help solve for Angle EBA
(180-130)/2=x
This is because we know angle DBC is 130, so when that 's subtracted from the original amount we are left with 50 degrees for angle ABD. Then, since EB goes through the middle of it, we know that Both ABE and EBD are equal to half of 50 which is 25.

Therefore, <EBA is equal to 25 degrees

Answer from: Quest

step-by-step explanation:

hello and welcome!

so, when we see the words "proportional" along with a table, we need to know that we're looking numbers that divide by the same thing.

looking at this table, we simply have to do a trial and error, and divide to see which numbers have the same quotient. if you look at choice a & c, they both have equal quotients for three of the numbers, with one exception, so those can't be the answer. looking at b, there is no similarity, so that can't be it. then, we see d; if you divide all the numbers in the table, you'll see that they all divide by two, which is a proportional relationship, and our answer!

$4/2 = 2\\7/3.5=2\\8/4=2\\10/5=2$

also, always remember that the x will always be the number that goes into y, and somewhere behind this table, is a formula. for this specific table, the formula would be:

$y=\frac{x}{2}$

since our x-value is being divided by two to get the y-value. and if they were to ask for more numbers in the series, this is the formula you would use to find them.
