Angles in polygons

A triangle is made up of the following: 73 degrees, 51 degrees and x degrees. Solve for x.

If a quadrilateral contains 3 right angles, what must the final angle be to form a quadrilateral?

If the angles in a decagon are the following: 73 degrees, 293 degrees, 203 degrees, 9 degrees, 29 degrees, 184 degrees, 173 degrees, 93 degrees, 208 degrees, y degrees. Solve for y.

Is it possible to have two obtuse angles in a triangle?

You are told that V + W + X + Y + Z = total interior sum of a pentagon. If V = 90 degrees, W = 110 degrees, X = 10 degrees, Y = 300 degrees, what would Z be?

If I split a 7 sided shape into 5 triangles, I have done the correct process to find the total interior angles within the shape.

Which of the following WOULD give you the total interior angles within a n-sided polygon?

Which of the following WOULD NOT give you the total interior angles of a n-sided polygon?

The sum of the total interior angles in a 30 sided shape is...

What would be the correct calculation to work out the total sum of the interior angles in a decagon?
