Answer:

Vertical and Supplementary

Step-by-step explanation:

Vertical:

each of the pairs of opposite angles made by two intersecting lines.

Supplementary:

Two Angles are Supplementary when they add up to 180 degrees. These two angles (140° and 40°) are Supplementary Angles, because they add up to 180°: Notice that together they make a straight angle. But the angles don't have to be together.

as the schools sign language interpreter kiran gets paid 35.50 for every parent-teacher conference that he attends. He also gets
yKpoI14uk [10]

<u>The interpreter attended </u><u>22 parent-teacher conference</u><u> and </u><u>5 school related assembly</u>

To solve this problem, we would write out two set of linear equations.

The data given on this problem are

  • parent-teacher conference = $35.50
  • school related assembly = $42
  • The total number of engagements = 27

Let x represent the number of parent-teacher conference

let y represent the number of school related conference

<h3>Equations</h3><h3>x+y = 27...equation (i)\\35.50(x)+42y=991...equation(ii)</h3>

From equation (i)

x+y  = 27\\x = 27-y...equation(iii)\\

Put equation(iii) into equation (ii)

35.50x+42y=991\\35.50(27-y)+42y=991\\958.50-35.50y+42y=991\\6.50y=991-958.50\\y=5

Put y = 5 into equation 1

x+y=27\\y = 5\\x+5=27\\x=27-5\\x=22

From the above calculations, he attended 22 parent-teacher conference and 5 school related assembly.
