Answer:

AC=6. I think, because ABC - isosceles, so two sides must have same lengths.

Answer:

1. TRIANGLE ABC IS SCALENE TRIANGLE.

2.TRIANGLE ABC IS RIGHT ANGLED TRIANGLE.

3. AC = 6

Step-by-step explanation:

Triangle ABC.

m<BAC = 50°

If m<ACB = 30°

TRIANGLE ABC IS SCALENE TRIANGLE.

proof: 50+30+x= 180

X= 180-80

X= 100

In SCALENE, all sides are unequal.

Triangle ABC.

m<BAC = 50°

If m<ABC = 40°

TRIANGLE ABC IS RIGHT ANGLED TRIANGLE

Proof: 50+40+x= 180

X = 180-90

X = 90

Triangle having any angle equal 90 is a right angle triangle.

If triangle ABC is isosceles, and AB = 6 and BC = 4, then AC = 6.

In isosceles triangle, two adjecent sides in contact with the angle that is not equal to the others are equal.
