Question

the measure of ∠dbz can be calculated. the measure of ∠dbz is ° because ∠dbz and are

Explanation:

Step1: Identify angle - relationship

We know that a straight - line forms an angle of 180°. At point B, the angle on the straight - line HC is 180°.

Step2: Calculate ∠DBZ

Since ∠DBZ+63° = 180° (linear pair of angles), then ∠DBZ=180° - 63°.
$180 - 63=117$

Answer:

117
