Math Problem Statement

Given that Ray BE bisects Angle ABD:

If the measure of Angle ABE = (6x + 2) degrees and the measure of Angle DBE = (8x - 14) degrees.

Find the measure of Angle ABE: degrees

Solution

Since Ray BEBE bisects Angle ABDABD, it means that:

ABE=DBE\angle ABE = \angle DBE

Given the expressions for the angles:

ABE=6x+2\angle ABE = 6x + 2 DBE=8x14\angle DBE = 8x - 14

Since ABE=DBE\angle ABE = \angle DBE, we can set the two expressions equal to each other:

6x+2=8x146x + 2 = 8x - 14

Now, solve for xx:

  1. Subtract 6x6x from both sides: 2=2x142 = 2x - 14

  2. Add 14 to both sides: 16=2x16 = 2x

  3. Divide by 2: x=8x = 8

Now, substitute x=8x = 8 back into the expression for ABE\angle ABE:

ABE=6(8)+2=48+2=50 degrees\angle ABE = 6(8) + 2 = 48 + 2 = 50 \text{ degrees}

Thus, the measure of ABE\angle ABE is 50 degrees.
