Coefficients are y and x
Variables are the number with the letters
The terms are the numbers
Answer:
a. x=65 because of vertical angle theorem,c. 44, b.y= 71 because of triangle angle sum theorem
Step-by-step explanation:
c. corresponding angle theorem and supplementary angle theorem so z+65+71=180 meaning z= 44
