Answer:
$191.70
Step-by-step explanation:
total amount spent = cost of medicine + cost of tax + cost of shipping
cost of tax = 0.05 x $180 = $9
cost of shipping 0.015 x $180 = $2.70
total cost = $180 + $9 + 2.70 = $191.70

Answer:
x = 20°
y = 70°
Step-by-step explanation:
the angle adjacent to the 40° angle must be 140° because the two angles form a straight line (which contains 180°)
in the isosceles triangle with the 'x', that means the other two angles must be equal and are (180-140) ÷ 2, which equals 20°
to find 'y', consider the larger right triangle with angles of 90° and 20°; angle y must equal 180 - (90 + 20) = 70°
