Answer:
6:6=x
7:16=y
8:20=z
Step-by-step explanation:
For 6, since BD is a perpendicuar bisector, that means 15x=90. Divide 90 by 15 and you get 6
for 7, if bd is a angle bisector, you can set 3y=48. divide 48 by 3 and you get 16
for 8, since Bd is a median, you can set 2z-3=z+17. Isolate the variable and you will get 2z-z=17+3. Add like terms together and you get z=20
Just so you know, a perpendicular bisector will make both angles equal to 90, an angle bisector make both angles equal to each other, and medians make it so that it hit a line in the center therefor you can set both sides of the line to be equal
