1. Given any triangle ABC with sides BC=a, AC=b and AB=c, the following are true :
i) the larger the angle, the larger the side in front of it, and the other way around as well. (Sine Law) Let a=20 in, then the largest angle is angle A.
ii) Given the measures of the sides of a triangle. Then the cosines of any of the angles can be found by the following formula:
a^{2}=b ^{2}+c ^{2}-2bc(cosA)
2.
20^{2}=9 ^{2}+13 ^{2}-2*9*13(cosA) 400=81+169-234(cosA) 150=-234(cosA) cosA=150/-234= -0.641
3. m(A) = Arccos(-0.641)≈130°,
4. Remark: We calculate Arccos with a scientific calculator or computer software unless it is one of the well known values, ex Arccos(0.5)=60°, Arccos(-0.5)=120° etc

The amount of profit the spirit club make on each shirt sold at the end of the year is = $2
<h3>Calculation of profit</h3>
The quantity of shirt bought by the club = $8 per shirt
At the end of the year they sold the shirts at discount of %25 each.
That is 25/100 × 8
= 200/100
= $2
Therefore, they made profit of $2 for each shirt they sold at the end of the year.
