Question

what is the measure ??​

Answer 1

Answer:

∠x = 92°

Step-by-step explanation:

Supplementary means that the angles add up to 180°. Since one of them equals 88°, the other one or ∠x equals:

$180-88 = 92$

So, ∠x = 92°

Answer 2

Answer:

x = 92

Step-by-step explanation:

Supplementary angles add to 180 degrees

x+y = 180

x+88=180

Subtract 88 from each side

x+88-88=180-88

x = 92
