Answer 1

Answer:

a+b+c+? = 180

4x+3x+2x+? = 180

9x+? = 180

? = 20. answer.

Answer 2

Answer:

angle CAD = 140degree

step by step.....

by angle sum property-----

angle A+B+C = 180 degree

4x+2x+3x= 180 degree

9x= 180 degree

x= 180/9

= 20degree

Hence

angle......

A= 2×20=40

B= 3×30= 90

C = 4×20= 80

angle CAD= SUM OF TWO INTERIOR OPPOSITE ANGLES

angle CAD= angle C+angle B

= 80+60

140 degree...

hope It'll help u....plzz..plzz...mark me as brainliest....
