An equation is a mathematical statement formed when an algebraic expression is equated by an equal sign by a constant or algebraic expression.

It is given that weekly earnings of Tom is $650

Tax deduction is 16.5%

Let the amount of Tax deduction is represented by $x

Then the equation formed is;

x = 16.5% 650

x = 16.5*650/100

x = $ 104

Now, subtract 104 from 650

$546

Therefore Tom paid $ 546 as tax deduction each week.

Answers

Answer:

a straight line has an angle of 180

therefore 180-109=71

71÷2 = 35.5

x is 35.5 degrees

The measure of x is 29 degree.

What is Parallel line?Straight lines that are always the same distance apart from one another are called parallel lines.No matter how far apart they are from one another, parallel lines can never intersect.

As, Parallel line have property

Any two lines are considered to be parallel if the angles formed by them are equal.If the Opposite interior angles formed by two lines are equal, they are said to be parallel.If the Opposite exterior angles formed by two lines are equal, they are said to be parallel.If the Successive interior angles on the same side of the transversal are additional, two lines are said to be parallel.

As, <CBA = <BAD (Alternate Interior Angle)

So, <BAD = 42

Now, <BAD + <BAC + <CAE = 180 (Linear Pair)

42 + 109 + x = 180

151 +x = 180

x = 180- 151

x = 29
