what is the value of z? 34° 63° z

Explanation:

Step1: Recall angle - sum property

The sum of angles around a point is 360°.

Step2: Set up the equation

Let the unknown angle be (z). We have (z + 34^{\circ}+63^{\circ}= 360^{\circ}).

Step3: Solve for (z)

(z=360^{\circ}-(34^{\circ} + 63^{\circ})) (z = 360^{\circ}-97^{\circ}) (z = 263^{\circ})

Answer:

263
