How to work out the acceleration of an object I got given this question and im just lost.

An object that weighs 25 kg experiences two perpendicular
  forces of 80N and 50N respectively. 
What's the acceleration that object gets?

What i don't understand is how i would use that information to work out the answer.
Any Thought, I would like to know how you worked it out and what the answer is..
I believe that it would be 30N as gravity is not in play here, nor would be mass of the object affect the acceleration due to unknown factors.
 A: One way we can set up - and solve - this problem is to think of things visually as vectors. 


*

*Draw a dot and label it "m = 25 kg"

*Draw a short arrow in any direction (how about directly north?). Label it "$F_1 = 50$ N."

*Start from the dot again and draw a longer arrow perpendicular to the first arrow. This can be either west or east because the question didn't specify directions. Label it "$F_2 = 80$ N." We drew it longer because 80 > 50.

*Vector addition says that when adding vectors visually, we draw one vector $A$ point to tip, then add another vector $B$ by drawing another dot at the most recent tip and draw out the 2nd vector. How long the arrow is = the magnitude of the vector ("how much"); direction of arrow = direction (could be described in unit vectors or angle from one of the axes to the vector). So, once you place the vectors connected like I said, what shape does it look like?

*Use a famous theorem to the resulting vector $C$ (which we draw from the point of $A$ to the tip of $B$).

*Now that we have the magnitude of $C$ we can plug this into Newton's 2nd Law: $F = ma$. Solve for $a$.

A: The acceleration experienced by a body along the line of force can be calculated from Newton's 2nd law, that is:
$F = ma$
Rearranging,
$a = F / m$
So, you need to divide the sum of forces experienced by the body in a particular direction divided by its mass to calculate the acceleration. 
A: Provided that these 2 perpendicular forces are the only forces acting on the body, there resultant can be easily found by parallelogram law of vectors. 
Using it i got the acting force as 94.34N and dividing by mass i got the acceleration as 3.77m/s2.
Note : Fnet^2 = F1^2 + F2^2 (from parallelogram law when angle between vectors is 90degrees)
