In ΔABC, the lengths of a, b, and c are 22.5 centimeters, 18 centimeters, and 13.6 centimeters, respectively.
Irina-Kira [14]
Given the values of the three sides of the triangle, we can apply the Cosine Law to find the angles of the triangle. Recall that for we can express the value of c through the equation below.

c^{2} = a^{2} + b^{2} - 2abcosC

Rearranging this equation, we can find the value ∠C as shown below.

\cos C = \frac{a^{2}+b^{2}-c^{2}}{2ab}
C = cos^{-1} (\frac{a^{2}+b^{2}-c^{2}}{2ab})

We can apply the same reasoning for finding the value of ∠B as shown.

B = cos^{-1} (\frac{a^{2}+c^{2}-b^{2}}{2ac})

Plugging in the values of the sides (see image attached) from the given. It will now be straightforward to compute for ∠B and ∠C.

C = cos^{-1} (\frac{22.5^{2}+18^{2}-13.6^{2}}{2(22.5)(18)})
C \approx 37.19

B = cos^{-1} (\frac{22.5^{2}+13.6^{2}-18^{2}}{2(22.5)(13.6)})
B \approx 53.13

Answer: ∠C = 37.19° and ∠B = 53.13°

cody is saving money for a new skateboard that costs $77.99. He already has $20 in his savings account. He earns $6 for every la
iVinArrow [24]
Cost of the skateboard = $77.99

Amount that he already has = $20

 $77.99 - $20 = $57.99
He still needs <u>$57.99</u>

He earns $6 for every lawn he mows.

$57.99  ÷ 6 =  9.65
He needs to move <u>10 lawns </u>to earn that $57.99.

He can mow 3 lawns a weekend.

10 ÷ 3 = 3 1/3 
He needs to work on <u>4 weekends</u> to mow the 10 lawns.


Answer: It will take him 4 weekends to save enough to buy the skateboard.
