Answer:

108

Explanation:

To find the area of the shape we have to first know the equation for sum of interior angles which is (n-2) x 180, where n is the number of sides!

We know that our shape has 5 sides (pentagon), so we have to plug this into our equation

  • (5-2) x 180 = 540

Now we have to find the sum the sum of the angles we are given

  • 113 + 98 + 103 + 118 = 432

And take that away from 540

  • 540 - 432 = 108

Our answer is 108!

Hope this helps, have a lovely day! :)
