2

Step-by-step explanation:

2 is the answer of the above

x=5

Step-by-step explanation:

We know that corresponding sides will have the same angles. In this case it's 12 and 12+3=15. That means that larger triangle is 15/12=5/4=1.25 times larger.

So we apply that for 3x+1 as well.

1.25(3x+1)=4x

3.75x+1.25=4x

.25x=1.25

x=5

step-by-step explanation:

two pairs of adjacent sides are of equal length. this implies that one diagonal divides the kite into congruent triangles, and so the angles between the two pairs of equal sides are equal in measure. it also implies that the diagonals are perpendicular.
