If m鈭�4=2m鈭�3find m鈭�6

Short Answer

Expert verified

Measurement of鈭�6is 60

Step by step solution

01

Step 1. Observations from figure

  • Arrowheads are shown on lines Iand P, so these lines are parallel
  • Line tis transversal to the parallel lines IandP
02

Step 2. Find m angle 3

鈭�3and 鈭�4forms linear pair, so sum of these angles is 180

m鈭�3+m鈭�4=180m鈭�3+2m鈭�3=180

3m鈭�3=180

m鈭�3=1803

m鈭�3=60

03

- Find m angle 6

鈭�3and data-custom-editor="chemistry" 鈭�6forms a pair of alternate interior angles, so measurement of these angles are equal. m鈭�3=m鈭�6

Thus, m鈭�6=60
