Please help asap!! Pretty simple if you understand I guess lol

angle z = 52

Step-by-step explanation:

solve for t

t+58=2t-12

t+70=2t

70=t

plug in the value of t in t+58

(70)+58

=128

note that angle y and z make supplementary angles, so

180-128

=52

robert puts 2 in each row

yes because there is exactly one y value for every x value

for function there can't be more than one value for every x value
