Question

. Given that DAB is a straight line, find the value(s)
of the unknown(s) in each of the following figures.​

Answer 1

Answer:

Angle CAB = 78 DEGREE

ANGLE CAD= 102 DEGREE

Answer 2

Answer:

angle CAD = 102°

angle CAB = 78°

Step-by-step explanation:

Given:- angle ACB=55° & angle ABC=47°

Therefore, by angle sum property of triangle,we get

angle ABC+ angle ACB + angle CAB = 180°

55° + 47° + angle CAB = 180°

102° + angle CAB = 180 °

angle CAB= 180 -102°

angle CAB= 78 °

Since DAB is a straight line

therefore, angle CAB + angle CAD = 180°

78° + angle CAD = 180°

angle CAD= 102 °
