Question

Find the sum of the interior angles of the shape. Use the remaining angles to solve for x. Polygons Help91°120°899Sum of interior angles =degreesX =degrees

Answer 1

For this case we have 4 sides

Then the sum of the interior angles is givne by

`180(n-2)=180(4-2)=180\cdot2=360\text{ }`

Sum of interior angles is 360º

And if we solve for x we can do this:

360-91-120-89= 60

x= 60 º
