Question

I need the answer for question

Answer 1

DE║BC THEREFORE X = ∠ADE = 60°

AND Y = ∠C = 70°

NOW IN ΔADE BY ANGLE SUM PROPERTY

∠ADE + Z + Y = 180°

Z = 180 - 60 - 70

Z = 50°

Answer 2

Angle ADE is isoscele triangle

let Z and Y be x
a/q,
x + x + angle D= 180*(by A.S.P.T)
2x + 60*= 180*
2x= 180*- 60*
2x= 120*
x=120*/2
x=60*
so, angle Z=60*
angle Y =60*
angle Z= angle A
so,
angle A=60*
now,
angle A + angle B + angle C =180*(by A.S.P.T.)

60* + x + 70*=180*
x + 130*= 180*
x = 180*- 130*
x=50*
Hence,
angle Z= 60*
angle E=60*
angle B=50*

I hope it helps you
