Answer:
a ≈ 19.45
Step-by-step explanation:
<u><em>Law of Cosines</em></u>
a=c2+b2﹣2cbcosγ
=112+132﹣2·11·13·cos(108°)
≈19.45196

Answer:
94.2 cm^3.
Step-by-step explanation:
Volume of a cone = 1/3πr^2h
The radius of the cone = 1/2 * 6 = 3
So here the volume is:
1/3 * π * 3^2 * 10
= 94.247
25ml — you add up the two numbers in the ratio, and that makes 5 (2+3), you then need to make sure that your answer is a multiple of 5 while being in the ratio 2:3. You then add up the 2 colours of paint

Answer: SSS Postulate</h3>
The tickmarks tell us which pairs of sides are the same length.
- AB = BC due to the single tickmarks
- AD = CD due to the double tickmarks
So far we have two pairs of congruent sides.
The third pair of congruent sides are the overlapping or shared sides BD = BD which is true by the reflexive property (anything is congruent to itself).
Overall we have three pairs of congruent sides allowing us to use SSS. Each "S" stands for "Side".
