Given parallelogram ABCD. If m∠ACD = (7x – 12)° and m∠BDC = (10x + 5)°, find x. Write your response in the form x=.

Given:

In the parallelogram ABCD, m∠ACD = (7x – 12)° and m∠BDC = (10x + 5)°.

To find:

The value of x.

Solution:

The diagonals of a parallelogram are perpendicular bisectors.

Let O be the intersection point of the diagonals.

In triangle OCD,

      [Angle sum property]

Therefore, the value of x is equal to .

answer: 12

step-by-step explanation:

because yes

thats not a system of equations, that is a solution
