Question

ABCD is parallelogram what value of x if angle BCA (4x-2) and angle CAD = (x + 19) °​

Answer 1

Step-by-step explanation:

given angles are vertically opposite angles,

and we know that these angles are equal

so,. 4x-2=x+19

3x=21

x=7

4x-2= 4(7)-2. =26°

x+19= 7+19. =26°

hence, proved

Answer 2

REASONINGS:

1. Opposite angles of a parallelogram are congruent.
2. Angle sum property of a quadrilateral.
