Question

If angle BDC and angle ACB are right angles, then what is the measure of angle BCD?​

Answer 1

Step-by-step explanation:

angle ADC 90°

applying ASP in ∆ADC

angle ACD=40°

THEREFORE angle BCD=90-40=50°

Answer 2

Step-by-step explanation:

since ,in triangle ACD,

A + C + D = 180° [angle sum property]

50° + C + 90° = 180°

C + 140° = 180°

C = 180°-140°

C = 40°.

Therefore, angle ACD = 40°.

Given, angle ACB = 90°.

angle ACD +angle BCD = 90°

40° + angle BCD =90°

angle BCD = 90°-40°

angle BCD = 50°.
