a = 6.2
Solution:
Given ABC is triangle.
AC = b = 8, BA = c = 11, ∠A = 32.2°
BC = a
To find the length of a:
Law of cosines:






Taking square root on both sides of the equation.
a = 6.1464
a = 6.2
The length of BC is 6.2.
Answer:

Step-by-step explanation:
Tina started with $20, but had to spend $3.25 on the bat.
$20-$3.25 = $16.75, which is all she has left for rounds.
Each round costs $3.00
$16.75 divided by $3.00 comes out to 5.58 rounds, but since she can't play 1/2 a round, that means she could only play 5 rounds
5 rounds X $3.00 per round comes to $15.00
