You may or may not what this is, it's a cyclic quadrilateral.

A cyclic quadrilateral is a quadrilateral that can be inscribed in a circle where all four vertices are tangent to the circle.

Also, opposite angles of a cyclic quadrilateral always add up to 180 degrees.

1) We know 117 is the opposite angle, and the angles add to 180, so what is the missing? Pretty simple.

2) Same thing - 62 is the opposite angle, and the angles add to 180, so what is the missing?

You are very welcome!

\(a\times 10^n\)

a=4.8

480/4.8=100

10^n=100

n=2

4.8*10^2

You are very welcome!

This is an integer so it cannot be rounded.

Perhaps you want 0.27104?

Then it would be 0.2710 or just 0.271.

You are very welcome!
