first can you find the missing angle in the triangle?
OpenStudy (anonymous):
always remember that : the exterior angle = sum of the two interior opposite angles
OpenStudy (anonymous):
so the middle is 90

z= 72 + 45

how
OpenStudy (anonymous):
Z = 117 degrees
OpenStudy (rhystic):
So a straight line = 180 . a box at angle denotes 90 degrees. On that straight line you have 123 degree angle so what angle is left? (57) A triangle is 180 degrees. so 180 = 90 + 57 + z

but ill fa for the effort
OpenStudy (anonymous):
yes i did explain it

Exterior angle=sum of interior angles
\[123=90+Z\]\[Z=123-90=33\]
