Answer:
mABD=24
mDBC=24
Step-by-step explanation:
First, set up x+15 and 4x-12 as equivalent equations
Subtract x from both sides to get 3x-12=15
Add 12 to get 3x=27
x=9
Plug 9 into the original equations representing the measurements of angles
You should get 24 for both because bisected means both are congruent

pythagoras for h
h² = 8² + 8²
h = √2(64)
h = 8√2
Answer:
yes
Step-by-step explanation:
Yes, because x=4 so 3x=12 so 12+2=14
