Question

In figure AB parallel to CD,the value of x is. answer fast​

Answer 1

Step-by-step explanation:

Draw a line through x parallel to AB and CD

Then x=(180-140) + 35

= 40+35

=75 degree

Answer 2

$\large \sf \bold{ \star \: \: solution : }$

$\large \sf \mapsto \: \:given :$

• BEF = 140°
• FSC = 35°

$\\ \large \sf \mapsto \: \:costruction :$

Draw a parallel lime such that

• AB || FG || CD

$\\ \large \tt \: divide \: \: x \: \: into : \\ \\ \large \tt \: x_1 \: \: \: and \: \: \: x_2$

➢ y + 140° = 180°

• Linear Pair

y = 40°

$\\ \large \sf \mapsto \: x_1 = y = 40 \degree \\ \\ \large \sf \mapsto \: x_2 = 35 \degree$

• Corresponding angles

$\\ \large \looparrowright \: \sf \: x = x_1 + x_2 \\ \\ \large \sf \implies \: x = 40 \degree + 35 \degree$

x = 75°
