Question

Find the measure of angle Z.

Answer 1

is the same gig as before, the triangle has a total of 180°, so the angle across from Z is 180° - 72° - 45°, or 63°.

since Z and her sister angle are sitting pigeons on a flat-line, they add up to 180°, so Z is 180° - 63°.

Answer 2

We know that sum of interior angles in a triangle is equal to exterior angle.

Hence Z=45+72

Z=117

Hence final answer is angle z= 117 degree
