I need help with this 4 questions. Please, and thank you.

2) the answer would be 123 degrees. angle B and D are congruent (equal) so if you solve for A by setting them equal to each other, A would equal 12. then by plugging 12 back in as A, both angle B and D would equal 57 for each. the total degrees inside the quadrilateral is 360 degrees, and you already have 114 (57+57 from both B and D), so you would subtract 360-114 to find the sum of the remaining angles, and since the other two angles A and C are congruent too, 246 divided by 2 is 123.

3) x equals 3 and y equals 6. if you set both expressions that have the same variable equal to each other, then you just use basic algebra to solve for the variable. lines BC=AD, and lines AB=CD.

7) the answer is A, JL is congruent to LA. the diagonals given are congruent and intersect at A, and the sides of the quadrilateral have parallel congruent sides, then this diagonal is congruent too. try drawing it out

8) the area is 121. if ABCD is a square, that means all the sides are the same length, which means BC and CD are equal to each other. by setting those expressions equal to each other, you solve for x then plug the answer back into one expression to find the length of one side. the length times itself is the area.

i hope i helped you a lot :)
