Angle B equals 30 degrees angle c equals 45 degrees AB equals 20 degrees BC

Angle B equals 30 degrees angle c equals 45 degrees AB equals 20 degrees BC

Ad is perpendicular to BC and D is perpendicular to BC
From the angle B 30 ° AB = 20, BD = 10 √ 3 and ad = 10 can be obtained
So CD = ad = 10
BC =10√3 +10
