Answer 1

Hope you got it..........

Answer 2

CAD = EAF ( VARTICAL OPPOSITE ANGLE)

CAD = 30

IN angle ACD

A + C + D = 180 ( ANGLES PROPERTY)

30 + C + 90 = 180

120 + C = 180

C = 180 - 120

C = 60

ACD = 60

BCD is a straight line

so,

BCA + ACD = 180 ( by linear pair)

BCA + 60 = 180

BCA = 180 - 60 = 120

than, in ABC

A + B + C = 180 ( ANGLES PROPERTY)

X + X + 10 + 120 = 180

2X + 130 = 180

2X = 180-130= 50°

2X = 50

X = 50÷ 2

X = 25 PROVED
