All exterior angles of a regular polygon would equal 360 degrees. SO... based on that, one exterior angle would have to multiplied by whatever sum (whole number) to equal 360 degrees to find the number of sides. Here you divide 360 by one of the exterior angles, if it does not equal a whole number then it would be inaccurate.
In this case only 54 degrees would not fit into one of the exterior angles.
Answer: ||||||| <em>n=41° </em>||||||<em> m=59° </em>IIIII<em> </em><em>p=260° </em>IIII
Step-by-step explanation:
<em>Alternate angle:</em>
<em></em>
<em><m=<59°</em>
<em>m=59°</em>
<em></em>
<em><n=<41°</em>
<em>n=41°</em>
______________
<em>p+41°+59°= 360°</em>
<em>p+100°=360°</em>
<em>p=360°-100°</em>
<em>p=260°</em>
Answer:
-6
Step-by-step explanation:
this is in y=mx+b form, where m is the slope ! so m is -6

Answer:
8 and 13 years old respectively.
Step-by-step explanation:
Let r = age of Rachael
Let m = age of Monica
M = r + 5 ..........equation 1
r + m = 21 ............equation 2
Substituting equation 1 into equation 2;
r + (r +5) = 21
r + r + 5 = 21
Simplifying the equation, we have;
2r + 5 = 21
2r = 21 - 5
2r = 16
r = 16/2 = 8
To find the value of m;
From equation 1;
m = r + 5
Substituting the value of r;
m = 8 + 5
m = 13.
Therefore, Rachael is 8 years old while Monica is 13.
