Jana knows that in ∆LET and ∆PVC, ET ≅ VC, ∠L ≅ ∠P and ∠E ≅ ∠V. Which congruence postulate or theorem can be used to prove that
LiRa [457]

Answer:

SAA theorem

Step-by-step explanation:

The given data with regards to ΔLET and ΔPVC are;

ET ≅ VC

∠L ≅ ∠P

∠E ≅ ∠V

From the given relationship, we have that two angles and the adjacent (nonincluded) side to the two angles in ΔLET are congruent to the corresponding two angles and adjacent (nonincluded) side of ΔPVC

Therefore, the congruence theorem that can be used to prove that the two triangles are congruent is the Side-Angle-Angle (SAA) congruency theorem

The SAA congruency theorem states that, two triangles that have two angles and a nonincluded side on one triangle being congruent to the corresponding two angles and a non included side on the other triangle, then the two triangles are congruent.

The product of two consecutive odd integers is 63. If x is the smallest of the integers, write an equation in terms of x that de
N76 [4]

9514 1404 393

Answer:

  • x(x+2) = 63
  • 7, 9
  • -9, -7

Step-by-step explanation:

If x is an odd integer, the next greater odd integer is x+2. The product is said to be 63, so the equation is ...

  x(x +2) = 63

__

The equation can be rewritten as ...

  (x +1)² = 64

  x = -1 ±√64 = -1 ±8

The positive solution is x=7, so the positive set of integers is {7, 9}.

The negative solution is x=-9, so the negative set of integers is {-9, -7}.
