100 POINT QUESTION<br> Which postulate or theorem can be used to prove △ABC ≅ △KLM?

Solnce55 [7]

Answer:

ASA congruence theorem

Step-by-step explanation:

Given two triangles ABC and KLM.

In ΔABC and ΔKLM,

m∠CBA = m∠MLK (given angle)

BC = LM (given side)

m∠CAB = m∠MKL (given angle)

Therefore, ΔABC ≅ ΔKLM (by ASA congruence theorem)

Hence by ASA congruence theorem ΔABC ≅ ΔKLM.

$x = \sqrt{3}$

Step-by-step explanation:

Given:

$\sin(ABC) = \frac{AC}{AB}$

$= > \sin(60) = \frac{3}{AB}$

$= >AB= 2 \sqrt{3}$

Now by Pythagoras theorem,

$AC^{2} + BC^{2} = AB^{2}$

Substituting values,

${3}^{2} + {x}^{2} = (2 \sqrt{3})^{2}$

$= > {x} = \sqrt{3}$

Hence, value of x is $\sqrt{3}$
