Since 8² + 15² = 17², triangle ABC is a right triangle.

Perimeter = a + b + c = 5 + 12 + 13 = 30.

Perimeter = 8 + 15 + 17 = 40 cm.

Since 8² + 15² = 64 + 225 = 289 = 17², triangle ABC is a right triangle.

Using Heron's formula, the semi-perimeter s = (8 + 15 + 17)/2 = 20. Area = √[s(s-a)(s-b)(s-c)] = √[20(20-8)(20-15)(20-17)] = √[20*12*5*3] = 60.

Since 8² + 15² = 64 + 225 = 289 = 17², triangle ABC is a right triangle.

The perimeter of a triangle is the sum of its sides. Therefore, perimeter = a + b + c = 5 + 12 + 13 = 30.

Using the cosine rule, cos A = (b² + c² - a²) / (2bc) = (15² + 17² - 8²) / (2 * 15 * 17) = 0.8.

Since the sides are in the ratio of a Pythagorean triplet (3, 4, 5), triangle ABC is a right triangle.

The sides satisfy the Pythagorean theorem, hence it is a right triangle.

A triangle with sides in the ratio 3:4:5 is a right triangle, as it satisfies the Pythagorean theorem.

Angle O = 180 - (angle M + angle N) = 180 - (45 + 45) = 90 degrees.

Using Heron's formula, s = (10 + 24 + 26)/2 = 30. Area = √(30(30-10)(30-24)(30-26)) = √(30*20*6*4) = 120 cm².

Since 8^2 + 15^2 = 17^2, triangle XYZ is a right triangle.

A real gas behaves most like an ideal gas under low pressure and high temperature conditions.

The magnetic field around a straight conductor is always perpendicular to the direction of the current.

The magnetic field inside a bar magnet points from the north pole to the south pole.

Using the right-hand rule, the magnetic field inside a current-carrying loop points into the plane of the loop.

Sound travels fastest in solids like steel due to closely packed molecules.

Convection is the mode of heat transfer where the temperature difference causes the fluid to move, transferring heat.

Radiation is the mode of heat transfer that occurs through electromagnetic waves, such as infrared radiation.

Plastic deformation occurs when the stress exceeds the yield point.

In aromatic compounds, the mesomeric effect dominates due to resonance stabilization.

The magnetic field is zero at the midpoint between two parallel wires carrying equal currents in opposite directions.

In PCl5, phosphorus exhibits dsp3 hybridization, forming five P-Cl bonds.

In C2H2, the carbon atoms are sp hybridized, forming a triple bond between them.

In PCl5, the phosphorus atom is sp3d hybridized, allowing it to form five P-Cl bonds.

In acetic acid, the inductive effect of the –COOH group influences the acidity of the compound.

H2 has a bond order of 1, indicating a single bond between the two hydrogen atoms.

A gas deviates most from ideal behavior at low temperatures and high pressures due to increased intermolecular forces.
