Question

find the value of x in the figure given ​

Answer 1

Answer:

20

Step-by-step explanation:

in ABC

A+B+C=180

80+30+ACB=180

ACB=180-110=70

ACB+X+ECD=180

70+90+X=180

X=180-160=20

Answer 2

Answer:

x = 20°

Step-by-step explanation:

Firstly, We will find ∠ACB

Let the unknown value be y

80° + 30° + y = 180° (Angle sum property)

110° + y = 180°

y = 180° - 110°

y = 70°

Now, to find ∠ACE, we have:

90° + y + x = 180° (Linear pair)

90° + 70° + x = 180°

160° + x = 180°

x = 180° - 160°

x = 20°

Hope it helps you!
