Answer:
Other side = 60
Perimeter = 150
Step-by-step explanation:
Using Hypothenuse formula
25²+B²=65²
625+B²=4225
B²=4225-425
B²=3600 (Bring Square to the other side to become Square root)
B=√(3600)
B=60
Perimeter:(Sum of all side)
60+65+25
150
21
answer 2) 24
after the dilation pt D is (8,-32)
after the dilation pt E is (-16,16)
if you use the distance formula for these two points you get which simplifies to 24
