Given: /|| m assume the transversal is perpendicular to m. find m1. a. 30 b. 45 c. 60

ANSWER


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,



This implies that,



We group like terms to obtain,



This means that,



We could have also used corresponding angles property, then

For being nice i appreciate it but abc
