Question

helpppp

four triangles are shown.

based on these triangles,which statement is true

A.w=75,because 45+60=105 and 180-75=75

B.w=105,because 180-(45+60)=75 and 180-75=105

C.w=285,because 45+60=105 and 105+180=285
D.w=165,because 180-60=120 and 120+45=165

Answer 1

The answer is B. w and z are supplementary angles (those which added together equal 180 degrees). Because of this, if we find out z (75 degrees) we can find w (105 degrees).
