<u>Answer-</u>

<em>The values of x and y are </em><em>13</em><em> and </em><em>24</em><em>, respectively.</em>

<u>Solution-</u>

From the attachment, l and m are parallel lines and

\Rightarrow (5x-8)+(4y+27)=180

\Rightarrow 5x+4y=161    ---------------------1

As, when a traversal line intersects two parallel lines, same-side interior angles are supplementary, or they add up to 180 degrees.

\Rightarrow (7x-31)+63=4y+27

\Rightarrow 7x-4y=-5     ---------------------2

As, an exterior angle is equal to the sum of the opposite interior angles.

Adding equation 1 and 2, we get,

\Rightarrow 5x+4y+7x-4y=161-5  

\Rightarrow 12x=156  

\Rightarrow x=13  

Putting the value of x in equation 1, we get

\Rightarrow y=24

Ab- 0.5b + 1/2 when a = 1 and b = 5
aniked [119]
Since you already know the values of a and b, all you have to do is split the problem into little parts and plug everything into its spot. AB would equal 1(5) which is 5. Athens 0.5b would equal, 0.5(5) to equal 2.5. So now your equation is 5-2.5+1/2 which equals 3.
