    Answer:

    30°

    Explanation:

    What we know:

    • We know that all angles in a triangle add up to 180°
    • We know that 1 of the 3 angles is 90°
    • We know that 1 one of the 3 angles is 60°

    What to find out:

    • What the last angle equals

    We used the information we know to give us this equation.

    90°+60°+x=180°

    We add 90° and 60° to give 150°

    150°+x=180°

    x must therefore be 30°

    Answer:

    30 degrees.

    Step-by-step explanation:

    Let the acute angle be x.

    Then as the 2 acute angles in a right triangle sum to 90 degrees,

    x = 90 – 60

    = 30.
