How do i find the measures of each numbered angle

The angles of every triangle add up to 180

Step-by-step explanation:

Angle 2=52) Add 71+57=128. 180-128=52

Angle 1= 123) Angle 57 and 1 are supplementary angles which means they add up to 180. So subtract 57 from 180 which will give you 123.

Angle 3= 29) Now that we know that angle 1 is 123, we add 123 and 28 which gives 151. Then subtract 180-151 which equals 29.

This problem was like a pattern. You work with one part at a time and then you unsolve each part :)

hello from mrbilldoesmath!

answer:

the domain is the set { -2, 0, 2, 3}

discussion:

the domain is the set of x values in the ordered pairs (x,y). taking the x, or first component, of each ordered pair gives   -2, 0, 2, 3.
