Cosine is the ratio of the adjacent side to the hypotenuse.
In short, we have this equation
cos(angle) = adjacent/hypotenuse
In the case of cos(A) = 18/19.5 we can see that
adjacent = 18
hypotenuse = 19.5
The side of 18 cm is next to angle 2, so the 18 cm side is adjacent to angle 2 (in contrast, the 7.5 cm side is the opposite leg in relation to angle 2)
So that's why the answer is angle 2
In other words, replace the '2' angle marker with 'A' to be able to write cos(A) = 18/19.5

Answer:
The answer to your question is 10¹/⁴
Step-by-step explanation:
Expression
To solve this problem use the law of exponents.
-Use the division rule of exponents.
If the base if the same in the numerator and denominator, it stays the same and the exponents are subtracted.
10¹ ⁻ ³/⁴ = 10¹/⁴ This is the result
