answer: they are supplementary angles

step-by-step explanation: 161+19=180. supplementary angles equal 180 degrees

there is no picture in order for this question to be answered

this is a direct variation proportion. y = kx

y is the total amount due, k is the constant of variation, and x is the number of texts sent.

plug in the 3.20 and the 16 to solve for the "k". this is the constant of proportionality. it is the value that will not change.

3.20 = k(16). solving you get $.20 per text.

the equation would then be y = .20x
