Larissa decided to build a kite using a new set of materials called Systekite. The challenge with the new material is that all dimensions are expressed algebraically. According to the instructions: AB = 2x + 3y + 4
AC = 4x + 2y - 1
BD = x - 2y + 7
CD = 2x - y - 3
m∡A = 3x + 2y + 15
m∡D = 5x - 2y + 27

part 1 answer = 8

part 2 answer = 72

step-by-step explanation:

part 1 explanation = add all of the numbers, then divide by how many numbers you have. so, 200/25 = 8.

part 2 explanation = not gonna lie, this is hard to explain, so just google how to do it.

∠lno ≅ ∠lnm

∠oln ≅ ∠mln

step-by-step explanation:

given   that triangle lno is congruent to triangle lnm.

we have to fill up the blanks in the given question.

according to above order of congruency   kept in mind we can say that

∠lno ≅ ∠lnm

∠oln ≅ ∠mln

ln ≅ ln due to common in both.

hence, by sas congruency,

the side angle side rule   states that if two sides and the included angle of one triangle are congruent to another triangle, then these two triangles are congruent.
