Arccos is the same thing as inverse cosine which is used when you are looking for an angle measure. Make sure your calculator is in degree mode. Hit 2nd button then cos and you will see this on your screen:
![cos ^{-1} (](https://tex.z-dn.net/?f=cos%20%5E%7B-1%7D%20%28)
and it is following the parenthesis there that you will enter your decimal. The inverse cosine of .67 is an angle measure of 47.93°
I rounded so 9.29
good night!!
Answer: Resultado=12 de comprimento.
Step-by-step explanation: 32 - 8 = 24 / 2 = 12.
Answer:
<A = 76°
<B = 63°
<C = 41°
Plug in the value of x
<C = 34 + 7
<C = 41°
Step-by-step explanation:
(sum of ∆)
Solve for x
![63 + 2x + 8 + x + 7 = 180](https://tex.z-dn.net/?f=%2063%20%2B%202x%20%2B%208%20%2B%20x%20%2B%207%20%3D%20180%20)
Add like terms
![78 + 3x = 180](https://tex.z-dn.net/?f=%2078%20%2B%203x%20%3D%20180%20)
Subtract 78 from each side
![78 + 3x - 78 = 180 - 78](https://tex.z-dn.net/?f=%2078%20%2B%203x%20-%2078%20%3D%20180%20-%2078%20)
![3x = 102](https://tex.z-dn.net/?f=%203x%20%3D%20102%20)
Divide both sides by 3
x = 34
<A = 2x + 8
Plug in the value of x
<A = 2(34) + 8 = 76°
<B = 63°
<C = x + 7
Plug in the value of x
<C = 34 + 7
<C = 41°
