Question

Find the value of x ​

Answer 1

Step-by-step explanation:

55+25+<ABD=180°(Sum of angles in a triangle )

80+<ABD=180

<ABD=180_80

<ABD=100

ABD+CBD =180°(Sum of angles in a straight line )

100+CBD=180

CBD=180_100

CBD=80°

CBD+40+<E=180°(Sum of angles in a triangle )

80+40+E=180

120+E=180

E=180_120

E=60°

E+x=180°(sum of angles in a straight line )

60+x=180

x=180_60

x=120°
