Question

Need help asap I don’t understand

Answer 1

x = 5

Explanation:

BD bisects angle ABC, which means it divides the angle into two equal parts.

So:

2x + 5 = 15

• Subtract 5 from both sides.

2x = 10

• Divide both sides by 2.

x = 5

To find angle measures, replace x with 5 in each expression:

∠ABD = 15°

∠DBC = 15°

∠ABC = 30°
