Answer:
70 and 110
Step-by-step explanation:
The two angles add to 180 degrees since they form a straight line
2x+10 +3x+20 =180
5x+30 = 180
Subtract 30 from each side
5x+30-30 =180-30
5x = 150
Divide by 5
5x/5 =180/5
x = 30
The left angle is 2x+10 = 2*30+10 = 60+10 =70
The right angle is 3x+20 = 3*30 +20 = 90+20 = 110
This is a trapezoid. It is a quadrilateral and only has 1 pair of parallel sides
The expression for finding the volume of a cube is s^3 in this case it is 16^3 or 16*16*16
You're simply divided each number by two
500/2= 250
250/2= 125
125/2= 62.5
62.5/2=?
