Question

In the figure, LABC = 40° then find LADC​

Answer 1

Answer:

40

Step-by-step explanation:

The angle ABC = The angle ADC (as, the base of the two triangles are occupying the same chord in the circle and the top vertex of the triangle is touching the circumference of the circle).

so, angle ADC = 40 degrees.

Answer 2

Answer:

40

Step-by-step explanation:

yes angle ADC is 40.because both right angle triangles are on same base.and both triangles similar and congruent triangles by AAA criterion.so angle ADC is 40
