    Triangles are always 180°, so you can do this:

    ∠A+∠B+∠C = 180°

    And you can plug in the angles that you have.

    x + 75° + 50° = 180°

    Then you get x by itself to find the measure of angle A.

    x = 55°

    Answer:

    The measure of angle A =x=55^{\circ}.

    Step-by-step explanation:

    Given a triangle ABC

    Measure of angle A=x

    Measure of angle B=m\angle B= 75^{\circ}

    Measure of angle C=m\angle C= 50^{\circ}

    We know that angle sum property of triangle

    m\angle A+ m\angle B+ m\angle C=180^{\circ}

    By using this property and substitute the value of given angles

    75+50+x=180

    By addition property we get

    125+ x=180

    x=180-125

    By subtraction property of equality

    Now, we get

    x=55^{\circ}

    Hence, the measure of angle A is x=55^{\circ}.
