13) Find the values of x and y.

x = 64°

y = 71°

Step-by-step explanation:

✔️x = 180 - 2(58) (isosceles triangle)

x = 180 - 116

x = 64°

✔️y + 45° + x = 180° (angles on a straight line)

y + 45° + 64° = 180° (substitution)

y + 109 = 180°

y = 180° - 109°

y = 71°

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.
