    Answer:

    Angle Sum Property :-

    • The sum of all the interior angles of a triangle is equal to 180°.

    Given :-

    • angle P = 70°
    • angle Q = 65°

    To Find :-

    • angle R

    Solution :-

    • angle R = 180° – ( 70° + 65° )
    • angle R = 180° – 135°
    • angle R = 45°

    Therefore, angle R is equal to 45°.

    Answer:

    Step-by-step explanation:

    In ΔPQR , ∠ P=70° , ∠Q=65°

    We have to find ∠R

    We know that sum of all interior angles of a triangle is 180°

    So,  ∠P + ∠Q + ∠R = 180°

    ∴70 + 65 + ∠R = 180°

    ∴ 135° + ∠R = 180°

    ∴ ∠R = 180 – 135 = 45°

    Ans : Measure of ∠R = 45°

    Hope it helps you…….. pls mark as the brainliest
