Kelly was asked to determine whether △KLN is congruent to △MNL. She noted that KL ≅ MN, LM ≅ KN, and that the three pairs of cor
Art [367]

Answer:

<h2>Kelly is wrong, with this congruent parts, we can conclude that triangles are congruent.</h2>

Step-by-step explanation:

To demonstrate congruent triangles, we need to use the proper postulates. There are at least 5 postulates we can use.

  • Angle-Angle-Side Theorem (AAS theorem).
  • Hypotenuse-Leg Theorem (HL theorem).
  • Side-Side-Side Postulate (SSS postulate).
  • Angle-Side-Angle Postulate (ASA postulate).
  • Side-Angle-Side Postulate (SAS postulate).

In this case, Kelly SAS postulate, because the corresponding sides-angles-sides are congruent, i.e., KL ≅ MN and LM ≅ KN, also, all corresponding angles are congruent.

So, as you can see, only using SAS postulate, the congruency can be demonstrated. (Refer to the image attached to see an example of SAS postulate)

james borrows Php 700000 and promises to pay the principal and interest at 15% compounded monthly. How much must he repay after
Licemer1 [7]

Answer:

A = $ 1,987,379.10 + 700,000= $2,687,379.10

Step-by-step explanation:

15% = 0.15 rate per tear

A = P (1+r/n)^nt

A = 700,000 (1+0.015/12)^12*7

A = 700,000 (1+0.0125)^84

A = 700,000 ((0.9875)^84

A = 700,000 (2.839113)
