Answer:
Option c) 119 degrees
Step-by-step explanation:
Given is a triangle BCD with exterior angle at B as ABD
Given are the angles of D and B.
We are to find the exterior angle measure ABD
WE can do this in two ways.
One method is to find ABD as supplementary of angle B since linear paid
Hence
[tex]ABD =180-61 =119[/tex]
II method is to use the fact that exterior angle is the sum of other two interior angles
Angle C = [tex]180-48-61\\= 71[/tex]
Angle ABD = sum of C and D
=[tex]48+71\\=119[/tex]
