Special right triangles Find the value of each missing variable

Mathematics
1 answer:
Shalnov [3]2 years ago
6 0

Hi!

Rules for solving 30-60-90 triangles are as follows:

* The hypotenuse is double the short leg.

* The short leg times √3 is the long leg

To solve then, we divide 4√21 by √3 and get 4√7. That is x, and to get y we multiply by 2. That is 8√7.

Hope this helps! :D

Based on the graph which congruence theorems or postulates are reasons why these graphs are equal?
AnnZ [28]

Triangles DEF and JKL can be proven to be congruent triangles based on:

C. ASA

E. AAS

F. LA

<h3>What is the ASA Congruence Theorem?</h3>

The ASA congruence theorem states that if two triangles that are have two pairs of corresponding congruent angles and a pair of corresponding included congruent sides, then both triangles are congruent to each other.

<h3>What is the LA Congruence Theorem?</h3>

The LA congruence theorem states that two right triangles are congruent if they have a pair of congruent legs and a pair of congruent angles that are corresponding to each other.

<h3>What is the AAS Congruence Theorem?</h3>

The AAS congruence theorem states that two triangles with two pairs of congruent angles and a pair of congruent non-included sides are congruent.

From the image given, triangles DEF and JKL can be proven to be congruent triangles using the LA, AAS, and ASA congruence theorems.
