Question

In a triangle ABC angle A=110 degree andAB=AC-DC find angle b and c

Answer 1

dear a triangle has 3 vertex so if they are a b c then
a=110' given
ab=ac
180'-110'=70'
angle b. and c=70/2=35'each

Answer 2

Let the triangle b and c be x.
:.sum of the triangle = 180°.
=> angle A + angle B = 180°.(A and B are adjacent angle).
110° + x = 180°
x= 180-110
x=70°
Angle B+C=180°. (Angle B and C are adjacent angle ).
70°+x=180
x=180-70
x=110°
