Answer: D. 70 degrees
Explanation: The sum of angles in any triangle is always 180 degrees. Therefore, angle C = 180 - (angle A + angle B) = 180 - (50 + 60) = 180 - 110 = 70 degrees.
Answer: D. 75
Explanation: The expression (x + y)(x - y) is a difference of squares, which simplifies to x² - y². Substituting the given values, we get 10² - 5² = 100 - 25 = 75.
Answer: B. 8 cm
Explanation: The area of a rhombus can be calculated using the formula (d1 * d2) / 2, where d1 and d2 are the lengths of the diagonals. Given the area is 24 cm² and one diagonal (d1) is 6 cm, we can solve for d2: (6 * d2) / 2 = 24, which simplifies to 3 * d2 = 24, so d2 = 8 cm.
Answer: A. (x + 1)
Explanation: By testing the roots, we find that (x - 1), (x - 2), and (x - 3) are factors, meaning x=1, x=2, and x=3 are roots. Plugging x = -1 into the polynomial gives (-1)³ - 6(-1)² + 11(-1) - 6 = -1 - 6 - 11 - 6 = -24, which is not zero, so (x + 1) is not a factor.
Answer: D. 150 cm²
Explanation: A cube has 6 equal square faces. The area of one face is side * side (s²). The total surface area is 6 * s². For a side length of 5 cm, the surface area is 6 * (5 cm)² = 6 * 25 cm² = 150 cm².
These 5 games share canonical tags with this one — same fanbase, adjacent angle. Each is a complete playable round in the same on-screen hosted format. Standard games use reusable host moments; only Smart Host-ready packs add prepared answer-aware reactions.
