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

Answer:
1/7 m
Step-by-step explanation:
Look at the picture above.
Hope this helps.
Step-by-step explanation:
By replacing x with 4, we get
- h(4)=1/4×4⁴-3×4³
- h(4)=1/4×256-3×64
- h(4)=64-192
- h(4)=-128
