Step-by-step explanation:

This is a help site, so I'll explain each property and see if you can match them yourself.

Associative property of addition, you can add 3 or more different numbers any which way, the sum will be the same.

Commutative Property of Addition - same as the associative property but with 2 numbers.

Identity Property of Multiplication - Any number multiplied by one is itself

Multiplicative Property of Zero: x * 0 = 0

Associative Property of Multiplication - Same as that of addition, yet with multiplication.

Distributive Property: Factoring Out.

EX: (12 x 15) = 3(4 x 5)

Answer:

Step-by-step explanation:

Known:

What to find = x

Exterior angle = 142

Right angle = 90

Unknown:

what unknown value is = ?

Interior angle = ?

1. Find the angle of the interior angles.

180 - 142 = 38

2. Add the two known angles

38 + 90 = 128

3. Subtract from 180

180 - 128 = 52

<h2>x = 52 is the answer.</h2>

Hope this helped,
