Answer:

(D) AAA

Step-by-step explanation:

Law of cosines: Law of cosines are mostly used in those cases which includes two sides and one included angle.

Thus, SAS and SSS triangle cases can be solved by the Law of cosines.

Law of sines: Law of sines can be used in those cases which includes one side and an angle opposite to that angle.

Thus, SAA triangle case can be solve by the law of sines.

Only AAA is the only triangle case which can neither be solved by Law of cosines nor by Law of sines.

Thus, Option D is correct.

$\bf{1) \ x^4-61x^2+900=0 }$

Applying the factorization method, for example:

$\bf{ 0=(x^2)^2-61(x^2)+900=(x^2-36)(x^2-25)}$

$\bf{\\ &=(x+6)(x-6)(x+5)(x-5); }$

$\bf{ x_1=6 \quad x_2=-6 \quad \ \ \ x_3=5 \quad x_4=5 }$

$\bf{2) \ x^4-25x^2+144=0 }$

Applying the factorization method:

$\bf{0&=(x^2)^2-25(x^2)+144=(x^2-16)(x^2-9) }$

$\bf{ =(x-4)(x+4)(x-3)(x+3); }$

$\bf{ x_1=4 \quad x_2=-4 \quad x_3=3 \quad x_4=-3 }$
