Answer:
its no solutions
Step-by-step explanation:
because u solve the 1st varibles in one of the equations,then subsitute the results into the other equations
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:
ur welcome
Step-by-step explanation:
Answer: Candace ate
servings.
Step-by-step explanation:
Given: Candace ate
cup of cereal.
The box of cereal states that 1 serving of cereal =
cup.
i.e. 1 cup =
servings [Multiply
both sides]
⇒
cup =
servings
=
servings [which is the number of servings she ate]
Hence, Candace ate
servings.
