Answer:
m = 8
Explanation:
We have
XZ is the bisector of angle WXY.
This means that XZ divides angle WXY into two equal angles, angle WXZ and angle ZXY.
Therefore, we have the following equation:
angle WXZ = angle ZXY
We can also write this equation as:
m(angle WXZ) = m(angle ZXY)
Substitute the given value:
(7m-13)° = (5m+3)°
7m - 13 = 5m + 3
Subtract 5m from both sides:
7m - 13 - 5m = 5m + 3 - 5m
2m - 13 = 3
Add 13 to both sides:
2m - 13 + 13 = 3 + 13
2m = 16
Divide both sides by 2:

m = 8
Therefore, the solution to the equation is m = 8.
