Answer:
Angle S is a straight angle.
Step-by-step explanation:
180° is a straight line.
Answer:
Yes,No,Yes,No,No
Step-by-step explanation:
Simply divide for example 64 divided by 4.
7 hours is 28 quarter hours. 50 is closer to 45 than 00 so it is. 75 hours. total is 28.75
I think this is the Answer

Answer:
Actually it's not polygon. it's a nonagon. With r=8.65mm″, the law of cosines gives us side a:
a=√{b²+c²−2bc×cos40°}
a=√{149.645−149.645cos40°}
Area Nonagon = (9/4)a²cos40°
=9/4[149.645−149.645cos40°]cot20°
=336.70125[1−cos(40°)]cot(20°)
Applying an identity for the cos(40°) does not get us very far…
= 336.70125[1−(cos2(20°)−1)]cot(20°)
= 336.70125[2−cos2(20°)]cot(20°)
= 336.70125[2−(1−sin2(20°))]cot(20°)
= 336.70125[1+sin2(20°)]cos(20°)sin(20°)
= 336.70125[cot(20°)+sin(20°)cos(20°)]mm²
