Question

if lines ab and cd intersect as shown find the value of x​

Answer 1

Answer:

In∆ECB

115°+30°+y=180(angle sum property)

y=180-145

y=35°

In∆ADE

x+y+25=180(angle sum property)

x+35°+25°=180°

x=180-60

x=120°

Step-by-step explanation:

let angle BEC=y

angleBEC=angleAED( vertically opposite angles)
