BD bisects angle ABC, measure of angle ABC=5x-4, and measure of angle CBD=2x+10. Angle ABC is a (n) _ angle

Since BD bisects ABC, CBD is half of ABC. Therefore, 2x+10 = (5x-4) / 2. We solve for x.

Multiplying by 2, we have:

4x+20=5x-4

Adding 4 and subtracting 4x, we see that:

x=24

Now, we substitute this in for x to find the value of ABC. We have:

5 * (24) - 4

120-4

116

Therefore, 116 is the value of angle ABC. Since 116 is greater than 90, ABC is an obtuse angle.
