Question

in tirangle ABC, AC=BC and BC is extended upto the point D. If triangleACD = 144 degree, then let us determine the angles of triangle ABC
​

Answer 1

Answer:

I really tried:

I can tell you their value added is 180 degrees.

If you assumed AB=CA as well triangle ABC would be equilateral with 3 angles of 60 degrees each; in which case the angles in triangle ACD would be: I really tried:

I can tell you their value added is 180 degrees.

If you assumed AB=CA as well triangle ABC would be equilateral with 3 angles of 60 degrees each; in which case the angles in triangle ACD would be:

Angle CAD 30 degrees

Angle ACD 120 degrees

Angle CDA 30 degrees

I also know that the length of AC will determine the angles BAC=BCA and they are equal to the addition of angles CAD+CDA.

That was all I could think of.

Angle ACD 120 degrees

Angle CDA 30 degrees

Answer 2

Answer:

if we assumed AC=BC means angle A = angle B means angle A = angle A now angle A+angle B = 144 then angle A+ angle A = 144 means 2angle A = 144 now angle A = 144/2 =72 = angle A and B = 72 and let us find angle C we know ; angle C + 144 = 180 now angle C = 180-144= 3
