c and  d are vertical angles. mc = 5x - 7 and md = 8x – 55.
what is mc? show your work.
i will give to the right answer.

Therefore m∠ C is 73°.

Step-by-step explanation:

Given:

∠ C and ∠ D are Vertical angles

m∠ C = 5x - 7

m∠ D = 8x - 55

To Find:

m∠ C = ?

Solution:

Vertical angles:

The angles opposite each other when two lines cross. They are always equal.

∠ C and ∠ D are Vertical angles  ...........Given

∴ ∠ C = ∠ D

Substituting we get

m∠ C  will be

Therefore m∠ C is 73°.
