Thank u! Find the measure of the exterior angle.

90

Step-by-step explanation:

The exterior angle is equal to the sum of the opposite interior angles

9x+9 = 45+5x

Subtract 5x from each side

9x-5x+9 = 45+5x-5x

4x+9 = 45

Subtract 9 from each side

4x+9-9 = 45-9

4x = 36

Divide by 4

4x/4 = 36/4

x = 9

The exterior angle is

9x+9

9*9+9

81+9

90

let m = monomial

let t = trinomial

so, m times t = t.

monomial times a trinomial = another trinomial.

yes because they have the same amount of green and blur marbles.
