Would assume the Polygon is an 18 sided regular polygon.
Exterior angle for regular polygon = 360/n (Sum of angles of exterior angles = 360°)
where n = number of sides.
Exterior angle = 360 / 18 = 20
Exterior angle = 20°
Sum of exterior angle + Interior angle = 180° (Both angles are on a straight line, so the sum is 180°)
Interior angle = 180° - 20°
Interior angle = <span>160°
</span>Hope this explains it.
14/15 - 5/12
Common denominator is 60.
56/60 - 25/60
= 31/60 as fraction.
= 0.516 as decimal.
M= y2 - y1/ x2 - x1
m= 9-9/-2-2
m= 0/-4
m= 0
The slope is 0
Answer:
x=11
m<a=80º
m<b=80º
Step-by-step explanation:
They are congruent so
8x-8=5x+25
8x=5x+33
3x=33
x=11
