Answer:

x = 3

Step-by-step explanation:

<u><em>Let's take the congruency of any side of these two triangles.</em></u>

<u><em>In boths Δs , </em></u>

=> 4x+1 = 13 (Taking this is rather more convenient)

=> 4x = 13-1

=> 4x = 12

<em>Dividing both sides by 4</em>

=> x = 3

Find the measure of angle BCD in the following parallelogram. what's does BCD equal
DiKsa [7]

Answer:

120 degrees

Step-by-step explanation:

This is a quadrilateral, and by definition, the sum of all the interior angles is 360. So, we can just sum up all the expressions and set them equal to 360:

2x + x + 2x + x = 360

Combine like terms and solve for x:

6x = 360

x = 360/6 = 60

<BCD = 2x = 2 * 60 = 120

Thus, the answer is 120 degrees.

Hope this helps!
