1/2 + 2/5 = 5/10 + 4/10 = 9/10
Let our basis be worth 1 dollar. A nickel's worth is $0.05. In order to come up with $1, the number of nickels should be:
Number of nickels = $1 * 1 nickel/$0.05 = 20 nickels
Thickness of 20 nickels = 20 nickels * 1.95 mm = 39 mm
Let's do the same for the quarters. Each quarter is worth $0.25.
Number of quarters = $1 * 1 quarter/$0.25 = 4 quarters
Thickness of 4 quarters = 4 quarters * 1.75 mm = 7 mm
Find the ratio of the two:
39 mm/7 mm = 5.57
Therefore, a stack of nickels is 5.57 times thicker than a stack of quarters worth one dollar.

Answer:
m∠A= 110°
Step-by-step explanation:
∠A+∠B=180°
5x+20+9x-92=180°
14x=180+92-20
14x/14=252/14
x=18
m∠A=5x+20
= 5(18)+20
=90+20
m∠A=110
