2x + 5x + 4 = 25
7x + 4 = 25
7x = 25 - 4
7x = 21
x = 21/7
x = 3 <==

Answer:
a=√2
Step-by-step explanation:
Given : ΔEGF ≅ ΔHKJ
where ∠G=∠K [right angle]
∠E=∠H=45°
And ∠F=180°-∠E-∠G [By angle sum property]
⇒∠F=180°-45°-90°
⇒∠F=45°=∠J [corresponding parts of two congruent triangles are congruent]
⇒ Both triangles are isosceles right triangles such that
JK=HK=b , EG=GF
and EF=JH
Now JK=HK= EG=GF=3√2
Now GF=3a=3√2
⇒a=√2
