Determine The Measures Of The Angles Marked With LettersNoteLines With Arrowheads Are Parallel class=

Sagot :

Determine the measures of the angles marked with letters.

1. Answer: [tex]\bold\blue{\tt{m∠m=120°}}[/tex]

Proof: Alternate Interior Angles Theorem

2. Answer: [tex]\bold\blue{\tt{m∠n=70°}}[/tex]

Proof: Alternate Exterior Angles Theorem

3. Answer: [tex]\bold\blue{\tt{m∠r=105°}}[/tex], [tex]\bold\blue{\tt{m∠s=75°}}[/tex]

Proof:

For ∠r, Linear Pair Theorem and Corresponding Angles Theorem

For ∠s, Vertical Angles Theorem
