Answer 1

Answer:

in figure 1

y = 70° and x = 35°

Explanation:

since AC=AB

ACB is an isosceles triangle

therefore Angle ACB = Angle ABC = y

by Angle sum property,

y+y+40=180

2y=140

y=70°

Angle ABC = 70°

Angle CBD = 180 - Angle ABC = 180-70=110°

since BC=CD

BCD is an isosceles triangle

therefore Angle BCD = Angle BDC = x

by Angle sum property,

x+x+110=180

2x=70°

x=35°
