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 answer: 25 degrees

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:

x=5 30 degrees

Step-by-step explanation:

theres 90 degrees in the right angle and you already have 60 degrees so you know it has to equal to 90 degrees so it has to be 30 degrees and 6 x 5 is equal to 30

What is the least common denominator of 4/7, 5/14, and 4/15.

lukranit [14]

Answer:

210

Step-by-step explanation:

Rewriting input as fractions if necessary:

4/7, 5/14, 4/15

For the denominators (7, 14, 15) the least common multiple (LCM) is 210.

LCM(7, 14, 15)

Therefore, the least common denominator (LCD) is 210.

Calculations to rewrite the original inputs as equivalent fractions with the LCD:

4/7 = 4/7 × 30/30 = 120/210

5/14 = 5/14 × 15/15 = 75/210

4/15 = 4/15 × 14/14 = 56/210
