The sum of measures of two alternate interior angles of two parallel lines with a transversal is 210°. What are the possible measures of the angles formed by the parallel lines and the transversal?

Respuesta :

Answer: [tex]\text{ Possible measures of angles will be } =105\textdegree \text {and 75\textdegree}[/tex]

Explanation:

Since sum of measures of two alternate interior angles of two parallel lines with a transversal = [tex]210\textdegree[/tex];

Since we know that alternate angles are equal to each other, [tex]\text{say x}[/tex]

∴ [tex]x+x= 210\textdegree[/tex]

⇒[tex]2x = 210\textdegree[/tex]

⇒[tex]x= \frac{210}{2}\\x=105\textdegree[/tex]

Hence ,

Possible measures of angles formed by the parallel lines and the transversal will [tex]105\textdegree[/tex] and [tex]180\textdegree - 105 = 75\textdegree[/tex].
