In figure $h$ ,
given $A B | | C D$ then find the following giving reason.
If $∠ 1 = (120 - x)^{o}$ and $∠ 4 = 54^{o}$
Then find the measured of $∠ 1$ and $∠ 5$ where $∠ 5 = 5 x^{o}$ .

From the figure $∠ 1 + ∠ 4 = 180$
Given $∠ 1 = 120 - x ∠ 4 = 54$
$120 - x + 54 = 180$
$x = 174 - 180 = - 6$
$∠ 1 = 120 - (- 6) = 126 °$
Given $A B ∥ C D$
$∴ ∠ 1 = ∠ 5$
$∠ 5 = 126 °$

In figure h, given AB||CD then find the following giving reason.If ∠1=(120−x)o and ∠4=54oThen find the measured of ∠1 and ∠5 where ∠5=5xo.

From the figure ∠1+∠4=180Given ∠1=120−x∠4=54120−x+54=180x=174−180=−6∠1=120−(−6)=126°Given AB∥CD∴∠1=∠5∠5=126°

In figure $h$ ,
given $A B | | C D$ then find the following giving reason.
If $∠ 1 = (120 - x)^{o}$ and $∠ 4 = 54^{o}$
Then find the measured of $∠ 1$ and $∠ 5$ where $∠ 5 = 5 x^{o}$ .

From the figure $∠ 1 + ∠ 4 = 180$
Given $∠ 1 = 120 - x ∠ 4 = 54$
$120 - x + 54 = 180$
$x = 174 - 180 = - 6$
$∠ 1 = 120 - (- 6) = 126 °$
Given $A B ∥ C D$
$∴ ∠ 1 = ∠ 5$
$∠ 5 = 126 °$
