Answer 1

Answer:

A. 51°

Step-by-step explanation:

By the theorem of intersecting secants.

$m\angle B=\frac{1}{2} (m\widehat{LW} - m\widehat{MU})$

$44.5\degree =\frac{1}{2} (140\degree - m\widehat{MU})$

$2\times 44.5\degree = 140\degree - m\widehat{MU}$

$89\degree = 140\degree - m\widehat{MU}$

$m\widehat{MU} = 140\degree -89\degree$

$m\widehat{MU} = 51\degree$
