Question

Find ‘x’ value in the figure.
​

Answer 1

Answer:

x = 120 degree

Step-by-step explanation:

ABC = 30 + x + 20

30 + x + 20 = 180《linear pair》

60 + x = 180

x = 180 - 60

x = 120

hope it will help u

Answer 2

Answer:

X=15 degree

Step-by-step explanation:

Firstly

In triangle ABE,

SUM OF ALL ANGLES OF A TRIANGLE IS 180 degree

Angle A + angle B + angle E = 180

Angle A = 180 - ( 30 + 100 )

Angle A = 50 degree

FINALLY

SUM OF ALL ANGLES OF A TRIANGLE IS 180 degree

Angle A + angle C + angle B = 180 degree

50 + 65 + 30+20+x = 180

x = 180 - ( 50 + 65 + 30 + 20 )

x = 15 degree
