Exercise 7 Page 481

The angles are congruent.

$w = 19$

Practice makes perfect

By the Vertical Angles Congruence Theorem, the two identifiable angles are congruent. Therefore we have that

5 w + 3 = 98 .

Let's solve the equation for

w .

5 w + 3 = 98

$LHS - 3 = RHS - 3$

5 w = 95

$LHS / 5 = RHS / 5$

w = 19
