Question

.62
In Fig. 63.
cio63, if AB || CD, the value of xis
(b) 35
(a) 25
(c) 15
(d) 20
3x
55°
2x​

Answer 1

Answer:

angle bcd = 3x

angle abc = 3x(alternate angles)

2x+3x+55=180(sum of all angles of triangle is 180)

5x=180-55

x= 125/5

x= 25

Plz mark it as BRAINLIEST

Answer 2

1. angle ABC will equal to angle DCB
2. due to alternate int angle
3. then in triangle ABC 2X+3X+55=180
4. then X=25
