cos = adj/ hypotenuse
Cos A = 30 /34
Simplifying
Cos A = 15/17
You can write both numbers as fractions:
Dividing by a fraction is the same as multiplying by its inverse, so we have
We can cross-simplify the 10's and we have
The missing angle is 49 :)

Step-by-step explanation:
We have been given that the number of raisins in a box of a popular cereal is normally distributed, with a mean of 133 raisins per box and a standard deviation of 10 raisins. My cereal box has 147 raisins.
To find the z-score for this box of cereal, we will use z-score formula.
, where,
z = Z-score,
x = Sample score,
= Mean,
= Standard deviation.
Upon substituting our given values, we will get:
Therefore, the z-score for this box of cereal is 1.4.
