Answer:
Explanation:
5) By midpoint theorem of triangles we get
2x=2(31) or x=31
8) By mid point theorem for triangles we get
6x+11=2(2x+23)
6x-4x=46-11
2x=33
x=16.5
Also since mid point bisects a side we get
2y+6=3y-9
y=15
9)By mid point theorem for triangles we get
x=2(25)=50
10)By mid point theorem for triangles we get
3x-6 =2x: 2x=2y+1
x=6: 12=2y+1
x=6 and y =5.5
