Question

Find the value of x.

Answer 1

x = 41

Explanation:

The angles shown are supplementary

Supplementary angles add up to equal 180

This means that x + 16 + 123 = 180

x + 16 + 123 = 180

Solve for x

Combine like terms ( add 16 and 123 )

x + 139 = 180

Subtract 139 from both sides

x = 41

Answer 2

9514 1404 393

Answer:

C) 41

Explanation:

The angles of the linear pair are supplementary, so you have ...

(x +16)° +123° = 180°

x = 41 . . . . . . . . . . . . . . divide by °, subtract 139
