Answer:

A. 15

Step-by-step explanation:

We are given a right angles triangle with hypotenuse length (c) = 23.5 and ∠B = 51°.

Now, using the trigonometric forms of a right angled triangle, we get,

\cos51=\frac{adjacent}{hypotenuse}

i.e. \cos51=\frac{a}{c}

i.e. 0.6293=\frac{a}{23.5}

i.e. a=0.6293 \times 23.5

i.e. a=14.8

So, the value of a = 14.8.

Hence, the nearest whole number to 14.8 is 15 i.e. a = 15.
