Question

In ∆ABC , AD perpendicular BC and AB =AC. If angle BAD = 40° , find angle B nd angle C.​

Answer 1

Answer:

angle B=angle C= 50°

Step-by-step explanation:

In triangle ADB

BAD+ADB+DBA=180° .. (SUM OF ANGLES OF A TRIANGLE)

So

40° +90° +DBA=180°

angle DBA=50°

Similarly

angle DCA=50°
