Answer 1

FIG1
in triangle BAD ANGLE A=X
ANGLE B=60
ANGLE D=180-90=90(SUM OF LINEAR PAIR IS 180)
SUM OF ANGLES IN A TRIANGLE =180
THERFORE ANGLE BAD =90+60+X=180
150+X=180
X=180-150
X=30
THERFORE IN TRIANGLE ADB ANGLE BAD=30

FIG2
IN TRIANGLE ADB
ANGLE ADB=180-90=90
(SUM OF LINEAR PAIR IS 180)
THERFORE ANGLE X =60+90+X=180
60+90+X=180
X=180-150
X=30
IN TRIANGLE ADB ANGLE Y =40+90+Y=180
Y=180-130
Y=50
THERFORE IN TRIANGLE ADB ANGLE X=30
AND ANGLE Y =50
