The only way I know how to do this is to use the cosine law.
b^2 = a^2 + c^2 - 2*a*c*Cos(105)
a = 12
c = 10
b = ??? (AC)
Cos(105) = - 0.25882

b^2 = 12^2 + 10^2- 2*10*12*(-0.25882)
b^2 = 144 + 100 + 240 * (0.25882)
b^2 = 244 + 62.117
b^2 = 306.12 Now take the square root
b = 17.50

Tyina is buying 12 shirts for the drama club. She will choose a style for the blank shirts and then pay an additional charge of
tensa zangetsu [6.8K]

Answer:

Cost of each blank shirt is less than or equal to $ 5.5

Step-by-step explanation:

Let x denotes cost of each blank shirt.

Total number fo shirts bought by Tyina = 12

Amount charged for each shirt to have the club logo = $2.75

So,

Amount charged for 12 shirts to have the club logo = 12(2.75)=\$33

As Tyina cannot spend more than $99,

12x+33\leq 99

Now solve the inequality.

12x+33\leq 99\\12x\leq 99-33\\12x\leq 66\\x\leq \frac{66}{12}\\ x\leq 5.5

So,

Cost of each blank shirt is less than or equal to $ 5.5
