16. 40°
17.125°
18.135°
19. x=96° 2x-50=142° x+40=136° x+20=116°
20. x=25° x+40=65° 2x+20=70° 3x=75° 6x=150°
X=-39/5 and y=10 :) i hope this helps you out !
A certain parallelogram has two pairs of parallel sides based on the following classifications is not correct Is Trapezoid
Answer:
x =14
Step-by-step explanation:
14x+24=18x-32
Subtract 14x from each side
14x-14x+24=18x-14x-32
24 = 4x -32
Add 32 from each side
24+32=4x-32+32
56 = 4x
Divide each side by 4
56/4 = 4x/4
14=x
In scientific notation, in would be 6.3825*10 to the 4th power
