Answer:
8
Step-by-step explanation:
x = centesimal angle (100 degrees in a right angle)
y = sexagesimal angle (90 degrees in a right angle)
x - y = 15
x×90/100 = y
x×9/10 = y
x - x×9/10 = 15
10x/10 - 9x/10 = 15
x/10 = 15
x = 150
y = 150×9/10 = 15×9 = 135
using centesimal system :
the sum of all external angles in a polygon is 400 degrees (a full circle).
one external angle is the complement of one internal angle to 200 degrees = 200-150=50 degrees.
to find the number of sides of the polygon we need to find the number of angles or corners. and that is how many external angles fit into the full circle.
n = 400/50 = 8
the polygon has 8 sides
Answer:
it would be c
Step-by-step explanation:
Answer:
ok, Im no exactly sure this is right becasue fractions aren't suppused to ever be a thing but here we go
Step-by-step explanation:
you want to get it to a same denominator.... so
2/3 times 5=10/15
3/5 times 5= 9/15
its asking about ATUL so, 10/15 divide 2=
ANSWER=5/15
hope this helped:)
Answer:
Me!
I have a pet hermit crab, his name is Mr. Lady.
I don't believe this is possible as the only two variables that are the same are I.
