Answer:

x=3

Step-by-step explanation:

Because the shape is a rhombus that means that WZ and XY are parallel

This means we can use the co-interior angles rule to conclude that ∠WZY and ∠XYZ add up to 180°

This means that ∠WZY is 44°

Because the shape in a rhombus ZX and WY are perpendicular

This means that ∠ZRY is a right angle (90°)

Because ZX and WY are perpendicular that means that ∠ZYX is split in half which makes ∠ZYW 68°

Because the angles in a triangle add up to 180°

(10x-8)+68+90=180

(10x-8)+158-158=180-158

10x-8+=22+8

10x/10=30/10

x=3

Amiraneli [1.4K]

Answer: her call lasted for 26 minutes.

Step-by-step explanation:

Let x represent the number of minutes for which her call lasted.

Rachel purchased a prepaid phone card for $30. Long distance calls cost 6 cents a minute using this card. Converting 6 cents to dollars, it becomes 6/100 = $0.06

This means that the cost of x minutes of long distance call is

0.06 × x = $0.06x.

If the remaining credit on her card is $28.44, it means that

0.06x + 28.44 = 30

0.06x = 30 - 28.44

0.06x = 1.56

x = 1.56/0.06

x = 26
