Given: /|| m Assume the transversal is perpendicular to m. Find m1. A. 30B. 45C. 60

Accepted Solution

A:
ANSWER
[tex] m \: < \: 1 = 60 [/tex]

EXPLANATION

Since the transversal is perpendicular to m,
it implies that the triangle formed by the perpendicular transversal, the slant transversal and the line m is a right angle triangle.



We use vertically opposite angles property to bring m<1 in to the right triangle.


We now use the sum of interior angles property to obtain,

[tex]m \: < \: 1 + 30 + 90 = 180[/tex]

This implies that,


[tex]m \: < \: 1 + 120 = 180[/tex]


We group like terms to obtain,

[tex]m \: < \: 1 = 180 - 120[/tex]


This means that,

[tex]m \: < \: 1 = 60[/tex]


We could have also used corresponding angles property, then

[tex]m \: < \: 1 + 30 = 90[/tex]


[tex]m \: < \: 1 = 90 - 30[/tex]



[tex]m \: < \: 1 = 60[/tex]
