A local shoe store is having a clearance sale on their summer shoes. The table below shows the sale price of each type of shoe. A customer bought 2 pairs of sneakers, 1 pair of flip-flops, and 1 pair of flats. The sales tax was $1.75. How much change did the customer receive from $30.00?
A. $13.58
A. $13.58

B. $21.16
B. , $21.16,

C. $7.09
C. $7.09

D. $22.91
D. $22.91

d. 145*2 is 290 than the total angle is 360 then minus 290 then divide by two

p

step-by-step explanation:

18 units²

step-by-step explanation:

first let's find altitude bd using the distance formula

d = √((y₂ - y₁)² + (x₂ - x₁)²)

bd = √((0 - -3)² + (0 - 3)²)

bd = √18

given the placement of points a and c, we can denote that point d bisects segment ac.

we will call ac the base.

using the distance formula

ac = √((0 - 6)² + (-6 - 0)²)

ac = √72

knowing our base and our height, we can plug these into our triangle area formula

area = (b * h)/2

area = (√18 * √72) / 2

area = (√1296) / 2

area = 36 / 2

area = 18 units²
