    Study Notes

    Geometry

    • The sum of all interior angles of a hexagon is unknown (question prompt).
    • In a right-angled triangle, the lengths of the sides opposite to the two acute angles are related by the Pythagorean theorem (no specific values given).
    • If one angle of a triangle measures 90 degrees, the other two angles can be any acute angles (less than 90 degrees) that add up to 90 degrees.

    Algebra

    • The solution to the system of equations 2x + y = 6 and x - y = -2 is unknown (question prompt).
    • The value of 3x + 2y when X = -4 and y = 2 is unknown (question prompt).

    Translation

    • একটি ষড়ভুজীৰ সকলো অন্ত:কোণৰ যোগফল কি? translates to "What is the sum of all interior angles of a hexagon?"
    • নিম্নিত 3, 4, আৰু 5 । 3 ॰5 ।5 ॰4 ।4 ॰3 বোৰো ট্ৰাইପ্লোনোরাণ্বিতে, a, b, আৰু c খন্তিটা? translates to "In a right-angled triangle with sides 3, 4, and 5, what are the values of a, b, and c?"
    • এখনাৰ এখনাৰ কি বিপৰীত কোণৰ যোগফল হ’ব? translates to "What is the sum of the opposite angles?"
    • এটি ষড়ভুজীৰ সকলো অন্ত:কোণেৰ যোগফল কি? translates to "What is the sum of all interior angles of a hexagon?"
    • X = -4, y = 2 সিস্তোন্ধা, 3x + 2y- খন্তি? translates to "What is the value of 3x + 2y when X = -4 and y = 2?"
