Answer:

cos^(-1)(12/13) = 22.62°

Step-by-step explanation:

Inverse trig functions are used to find angles. I was taught SOH CAH TOA: sine = opposite/hypotenuse, cosine = adjacent / hypotenuse, tan = opposite / adjacent.

Here, we have an adjacent side length and the hypotenuse. So we use inverse cosine.

Abe has a bag of marbles and wants to divide them into sets. The first set will have 2 marbles; the second set, 5; the third set

uranmaximum [27]

2 + 5 = 7

7 + 8 = 15

15 +11 = 26

11+3 = 14

26 + 14 = 40

so he has 5 sets
