Answer:
Step-by-step explanation: The answer is 5/11.
We know that
The sum of exterior angles of any polygon is 360 degrees.
Each exterior angle of a regular polygon = 360/n
where n is the number of sides.
<span>So
n = 360/20 = 18
</span>
the answer is the option
<span>b.18 </span>
Step-by-step explanation:
just add all the given angles and equate it with 540° and then find x
x/2 + x/2 + x - 25 + 100 + x - 15 = 540°
3x + 60 = 540°
3x = 540 - 60
x = 480/3
x = 160°
on checking, the given shape values of x-25 and x - 15 are both still obtuse angles thus the answer is correct.
its 2x8x8 is 2069 and add it up
M= 5 - y , 3 + a . ( hope I helped have a good day )
