Which trig ratio would you use to solve for the missing angle measure? 5 A) Cos! 26 26 B Cos-1 5 C) Sin 26 Sin? 26 5​

Choice A)  

You could also write which is the same as writing

Arccos stands for "arccosine", which is effectively the same as inverse sine. The notation means inverse cosine.

We use the cosine rule because

cos(angle) = adjacent/hypotenuse.

isolating the angle leads to

angle = arccos(adjacent/hypotenuse)

We can think of arccosine as an operation to undo the cosine function. It's similar to how division is the opposite of multiplication.

76%

step-by-step explanation:

24% are dogs and the remaining is 76% because 100-24=76
