Question

What is m/CBD?
pls help meeee

Answer 1

∠CBD is 145 degree.

∠ABD = 60 degrees (given)

∠ADB = 90 degrees (right angle)

∠BAD = 180 - ∠ABD - ∠ADB = 180 - 60 - 90 = 30 degrees

∠DBC = 35 degrees (given)

∠BDC = 90 degrees (right angle)

∠CDB = 180 - ∠DBC - ∠BDC = 180 - 35 - 90 = 55 degrees

∠CBD = ∠CDB + ∠ADB = 55 + 90 = 145 degrees
