Lines l and m are parallel. Parallel lines l and m are intersected by lines s and t. At the intersection of lines l, s, and t, c

lockwise from the top left, the angles are blank, 50 degrees, (x + 25) degrees, (2 x) degrees, 1, blank. Lines t, s, and m create a triangle with angles 1, 2, 3. Using the diagram, determine which statements are true. Select all that apply. m∠1 = 50° m∠3 = (2x + x + 25)° m∠2 = (x + 25)° m∠1 + m∠2 + m∠3 = 180° 50 + 2x+ x + 25 = 180

The true congruence statement is CW ≅ MQ ⇒ 2nd answer

Step-by-step explanation:

All the radii in the circle are congruent

From the attached figure

In circle B

∵ W, C, Q, and M lie on the edge of the circle

∴ BW, BC, BQ, and BM are radii

∵ All the radii in the circle are congruent

∴ BW ≅ BC ≅ BQ ≅ BM

∵ CW ≅ MQ ⇒ Given

∴ The true congruence statement is CW ≅ MQ
