10 sides 180(10-2) 1800-360=1440/10 = 144
Answer:
x= 10, y= 15
Step-by-step explanation:
because alternate interior angles are congruent
8x -10 = 7x
8x -7x = 10
x = 10
because straighht line form 180°
6y+20 +7x = 180
6y +20 +70 = 180
6y = 180 -90
y=90/6 = 30/2 = 15
V=h*w*l
V= 5*5*5
Volume= 125
Density= Mass*Volume
