Question

angle ABC is isosceles with the length of AB equal to the length of AC. The measure of angle A is 40* and points B,C, and D are collinear. What is the measure of Angle Acd

Answer 1

Hi Pal here is ur answer

Given: AB=AC

so <B=<C[angles opposite to equal sides are equal]

<A=40°

<A+<B+<C=180°[angle sum property]

40°+x+x=180°

2x=180°-40°

x=140°/2

x=70°=<B=<C

<BCA+<ACD=180°[ linear pair]

70°+y=180°

y=180°-70°

y=110°=<AND
