Question

Find the value of x!!

Answer 1

x=23

Explanation:

When realizing that the total degrees of a line = 180 you can set the equation to that number.

So that it would look like this-

3x+18+93=180

then you would combine like terms (18+93=111)

3x+111=180

Subtract 111 to start to get x by its self

180-111=69

then it would look like this

3x=69

Divide by 3 and then you get the correct answer of 23!

Answer 2

x=23°

Explanation:

93°+(3x+18)°=180°

93°+3x+18°=180°

111°+3x=180°

3x=180°-111°

3x=69°

x=69°:3

x=23°
