Answer:
Step-by-stepapex answer to the left of 9.9 and to the right of 9.3 explanation:
You have to add the like terms in the equation
These like terms are 8q^2 and 7q^2 because they both share q^2
The other like terms are -5q and -8q because they both have ‘q’
So add them and then add extra numbers (the 10) to the equation

Answer:
a) 150°
b) 30°
Step-by-step explanation:
It is easier to work the exterior angle first.
<h3>b)</h3>
The sum of exterior angles is 360°. The exterior angle at any vertex of a regular dodecagon will be 1/12 that:
360°/12 = 30° . . . the measure of one exterior angle
__
<h3>a)</h3>
The measure of an interior angle will be the supplement of the adjacent exterior angle.
180° -30° = 150° . . . the measure of one interior angle
