The answer is 24 sides
because the total amount of the exterior angles of a polygon is 360.
so if each exterior angle has a measure of 15:
A=1/2 b*h
So substitute it in 1/2*1/2*4
1/2*1/2= 1/4
1/4*4= 4/4= 1 so the entrance is 1 foot tall
Answer: 2. Linear pair postulate
4. 60 + mACB=180
5. mACB=120
6. definition of obtuse angle
Answer:
D
Step-by-step explanation:
the exterior angle ACD = m< 1+ m <2 = 56+54 = 110
Kelly has $10
- half: $10 - 1/2 x $10
$10 - $5 = $5
- one third: $5 - 1/3 x $5
$5 - $1.6667... or $5 - $1 and 2/3 = $3.33... or $3 and 1/3 or $10/3
She will have left $3.33 left, or $3 and 1/3
