the surface area of the cylinder is 0.5mm
Answer:
a = 60
b = 60
c = 120
Step-by-step explanation:
For a;
a + 120 = 180
This is because angles on a straight line are supplementary
a = 180-120
a = 60
a = b = 60
This is because they are corresponding angles and corresponding angles are equal
c = 120
This is because they are alternate exterior angles and alternate exterior angles are equal
X= 2.737 - look on the website "Tiger algebra for the answer by typing in the question
20% of $19,400 is $3,880
($19,400 / 5 = $3,880)
subtract 20% from the original value
($19,400 - $3,880 = $15,520)
it's now worth $15,520
