Question

find the value of x in each case​

Answer 1

Answer:

c is 180-(90+50)

c is 40

x is 180-(85+40)

x is 55

Answer 2

Answer:

• Here, in ∆DBF

∠DBF = 180 - 90 = 90° [Linear pair]

• Also, in ∆AEF

∠AEF = 180 - 85 = 95° [Linear pair]

• Again, in ∆AEF ,

∠AFE = 180 - (95 + 50) [Angle Sum Property]

　　 = 180 - 145

　 　 = 35°

• In ∆DBF,

∠x = 180 - (90 + 35) [Angle Sum Property]

　 = 180 - 125

　 = 55°
