Answer:
to know the summation of angles: (n-2)*180
here (n) represent numbers of sides
12)we have 5 sides (n=5)
(5-2)*180=540
x=540-(105+135+92+87)=121
13)we have 8 sides (n=8)
(8-2)*180=1080
x=1080-(116+158+141+124+136+132+129)=144
I hope it will help
Answer:
x = 1, y = -4
Step-by-step explanation:
set each equation equal:
-7x + 3 = -x - 3
-6x + 3 = -3
-6x = -6
x = 1
y = -7 + 3
y = -4
I believe you mean decalitre
A Decalitre is a metric unit capacity, Equal to 10litres
Answer:
7pi/5
Step-by-step explanation:
A coterminal angle is the original angle ± 2pi radians
So to find a coterminal between 0 and 2pi you will need to substract 2pi's until you get one within that interval
17pi/5 - 2pi = 17pi/5 - 10pi/5 = 7pi/5
and this is already the answer ^
