How many degrees are there in each exterior angle of an equilateral triangle

What is the equation of the linear function represented by the table?

Can someone me with #s 8, 9, and 11. with just one of the three also works. prove using only trig identities.

Scenario: susan wants to make 2 square flags to sell at a crafts fair. the fabric she wants to buy is 3 meters wide. she doesn't want any fabric left over. what's the least amount of fabric she should buy? question: which equation will susan solve her problem? note: let x represent the length of 1 side of the flag. options: 1) 2x^2 = 4x 2) 8 +2x = 2(4x) 3) 2 * 2 = 4 * 2 4) 4x^2 -2x = 0
