Hi, angle BCA = 27 degreeso in right triangle BDCangle BCD+angle BDC+angle CBD = 180 27+90+angle CBD = 180angle CBD = 63 degreenow in right triangle DEBangle DBE+angle DEB+angle BDE = 180 63+90+angle BDE = 180angle BDE = 27 degree

In the diagram m∠ABC = m∠BDC = m∠DEC = 90°. If m∠BCA = 27°, then find m∠BDE.
