Question

Can someone please explain to me how this is done

Answer 1

• See below.

Explanation:

We need to add up 4 angles to get 360.

Here is what you fill out for the missing boxes:

• 70 + 70 = 130
• 70 goes into the smallest angle.
• 115 + 115 = 230.
• If we do 120 or 130, It would make 370 or 390.
• 130 + 230 = 360.
• 50 + 50 = 100.
• Missing 50 goes into smallest angle.
• 130 + 130 = 260.
• 260 + 100 = 360.
