Which lines are parallel? Why?
Shtirlitz [24]

9514 1404 393

Answer:

  C) c || d by converse of corresponding angles

Step-by-step explanation:

Only corresponding angles where transversal b crosses lines c and d are shown. All answer choices involving a||b or interior angles can be eliminated from consideration.

The "corresponding angle" theorem tells you corresponding angles are congruent if the lines are parallel.

The converse of that theorem tells you the lines are parallel if the corresponding angles are congruent. Here, the angles are shown congruent, so the "converse" theorem applies.

olchik [2.2K]

Answer:

b = 45.9 - c

Step-by-step explanation:

A scalene triangle has non of its sides equal.

Perimeter = 54.6

side a = 8.7 cm

side b = unknown

side c = unknown

Perimeter of a shape is sum of all its sides.

Perimeter = a + b + c

54.6 = 8.7 + b + c

Making b the subject

b = 54.6 - 8.7 - c

b = 45.9 - c

The value of b is (45.9 - c)
