In the triangle ABC, ab = AC, ED is the vertical bisector of line AB, intersecting AB at point E, intersecting BC at point D. It is known that the degree ratio of ∠ bad to ∠ DAC is 1:3, and ∠ bad is calculated The degree of C

In the triangle ABC, ab = AC, ED is the vertical bisector of line AB, intersecting AB at point E, intersecting BC at point D. It is known that the degree ratio of ∠ bad to ∠ DAC is 1:3, and ∠ bad is calculated The degree of C

Because AB = AC, so ∠ B = C, and because ED is the vertical line of AB, so ad = BD, ∠ B = bad, let ∠ B = bad be x, so ∠ BDA = 180-2x ∠ C = b = x, and because ∠ bad: ∠ DAC = 1:3, so ∠ DAC = 3x, so in △ ADC
