Answer:
b
Step-by-step explanation:
3/2
60
40%=0.40
0.4x=24
x=24/0.4
x=60
Pretty sure is 15
90 divided by 6 is 15.
35
since m and n are the midpoints of ab and ac resistively
then ,bc=2mn=16
since m and l are the midpoints of ba and bc respectively
then, ac =2mn =10
then,nc =1/2 × 10 =5
similary, mb=6
then ,perimeter=nc+mb+mn+bc=5+6+8+16=35
