Answer:
its 40 degrees :)
Step-by-step explanation:
I think you will get x this way:
x=180°-140°
x=40°
80 cubes
volume of one small cube = 1 /2 × 1 / 2 × 1 / 2
= 1 / 8cm^3
let x be the number of cubes needed
1 / 8 × x = 10
x = 10 × 8
x = 80 cubes

acceleration=final velocity - initial velocity/total time
a=65-35/5
a=30/5
a=6
19/24
z-2/3=1/8
z=2/3+1/8
z=19/24
