The Pythagoras Theorem:

the base squared and height squared added is equal to the hypotenuse squared.

so

(x+6)² + (x+3)²= (x+9)²

x²+36+12x+x²+9+6x = (x+9)²

2x²+45+18x=x²+81+18x

x²=36

x=√36

X= 6

now

(x+6)= 12

(x+3)=9

(x+9)=15

haha sorry correct it pls

Which postulate or theorem proves that △ABC and △CDA are congruent?
Agata [3.3K]

Answer:

ASA Congruence Postulate ​

Step-by-step explanation:

Here if we clearly observe ∠DAC=∠BCA and ∠DCA=∠BAC

Also AC is a common side to both the triangles .

So by ASA congruence postulate we have that the ΔADC and ΔCBA are congruent.

ASA congruence postulate states that if two triangles have two angles and an included side same then both the triangles are congruent.
