I assume the question is multiply to -50 and add to +5... If so, the answer is +10 and -5. 10 (-5) = -50 .... and 10 + (-5) = +5

Answer:

$x=23.78$ cm

Step-by-step explanation:

As this problem is involving the adjacent and hypotenuse sides, we will be using the cosine function

We can setup an equation as follows

$cos(18)=\frac{x}{25}$

We can now solve for x

$x=25cos(18)\\\\x=23.776$

This rounds to

$x=23.78$
