Respuesta :
The measure of m∠8 = 137° due to corresponding angles are supplementary.
What are supplementary angles?
Supplementary angles are defined as when two angles add up to 180 degrees. Supplementary angles form a straight angle.
∴ m∠2 = m∠6 = 43° [ Corresponding angles }
Now, line L is a straight line and line T is on it,
∴ m∠6 + m∠8 = 180° [ Angles in linear pair ]
⇒ 43° + m∠8 = 180°
⇒ m∠8 = 180° - 43°
⇒ m∠8 = 137°
