What is the measure of ∠BCD? Enter your answer in the box. ° PLSSS help

denpristay [2]

It seems to be a tilted square, so all angles are the same.
$103 \times 3$
so maybe just multiply by 3 and get 309 since B, C, and D are three angles.
$103 \times 3 = 309$
I might be wrong but, the answer should be 309.

Step-by-step explanation:

well you know that the perimeter is the sum of all sides

so we have

$(2x)+(2x+4)+(2x+3)=(2x)+(2x)+(3x+1)\\\\2x+2x+4+2x+3=2x+2x+3x+1\\\\(2x+2x+2x)+(4+3)=(2x+2x+3x)+(1)\\\\6x+7=7x+1\\\\6x+7-1=7x\\\\6x+6=7x\\\\6=7x-6x\\\\x=6$
