Unfortunately, you haven't provided enough info. Could you possibly attach a sketch or photo image of this problem? What do you mean by 8_7?

What do you know about angle R? If this is one angle of a triangle, do you know the lengths of the opposite side, the adjacent side, the hypotenuse?

If so, share that info.

Can someone help me out with this

Answer:

$AB=4.41$

Step-by-step explanation:

Use the cosine ratio, $cosine=\frac{adjacent}{hypotenuse}$ . Insert the values:

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

Isolate x. Multiply both sides by x:

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

Divide both sides by cos 25:

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

Insert into a calculator:

$x=4.414$

Round to the nearest hundredth:

$x=4.41$

Done.
