Answer: 90 degrees
Explanation:
If a line bisects any angle, it means the two sides are equal, so we can set the equation equal to each other.
2x+15=3x
Subtracting 2x from both sides we get;
x=15
Now we can solve the problem by substituting 15 back in the equation
2(15)+15+3(15)
30+15+45
45+45
=90
The answer is 90 degrees.
