Question

Find angle DAB and angle DAB
Plz give me the solution

Answer 1

ABCD is a quadrilateral

so the sum of all angles of the quadrilateral is 360°

/_A=3x+4

/_B=50+x

/_C=5x+8

/_D=3x+10

/_A+/_B+/_C+/_D=360

3x+4+50+x+5x+8+3x+10=360

12x+72=360

12x=360-72

12x=288

x=24

now substitute value of x and find measures

Answer 2

Hello Dear
the solution is ready now
In triangle DAB
By using angle sum property
angle ADC+Angle DAB+ angle ABC=180°
=}3x+10+3x+4+50=180
=}6x+64=180
=}6x=180-64=126
=}x=126÷6=21

now put the value of x
angle ADC=3x+10=3×21+10=73
angle DAB=3x+4=3×21+4=67
and you you wanna check the answer add all of the angle and you will get 180
