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
Answer:
sin x° = Opposite / Hypotenuse
x = 3.38
Step-by-step explanation:
sin 70° = x / 3.6
sin 70° × 3.6 = x
x = 0.93969262079 × 3.6
x = 3.38289343483 ~ 3.38
(6k + 2) - (3k - 2)= 6k + 2 - 3k + 2 = 3k + 4
