Question

Does anyone know the answer?

Answer 1

Answer:

AB = 4.41

Step-by-step explanation:

→You are given the adjacent side and need to find the hypotenuse. For this, we use cos.

→Set it up, like so:

$cos25=\frac{4}{x}$

→To get rid of the x in the denominator, multiply everything by x:

$x(cos25=\frac{4}{x})$

$xcos25 = 4$

→Divide both sides by cos25:

x = 4.413

→Round to nearest hundredth:

x = 4.41
