Option A, 26°

Step-by-step explanation:

In the given right angle triangle we have to find the nearest measure of angle A.

By cosine law,

$cosA=\frac{Base}{Hypotenuse}$

$=\frac{18}{20}$

= ( 0.90)

A = $cos^{-1}(0.90)$

= 25.84°

≈ 26°

Option A is the answer.

There are 18 computers in all, and then 8 of them are over two years old. So the answer would be 8/18 reduced to 4/9
