    I got 109°

    To solve it, you just have to remember 2 rules.

    1. If you add all 3 angles of a triangle it must equal 180.

    2. Any angles that are made with a straight line...or a

    straight line with another line running through it forming

    2 angles. Well, those 2 angles must add up to 180°

    Here's an example of number 2:

    1st solve for Angle B

    m∠ABD = 180 - 34 - 30 = 116°

    solving for Angle DBC

    m∠DBC = 180 - 116 = 64°

    next solve the other Angle of smaller triangle Lets call it Angle BEC.

    m∠BEC = 180 - 64 - 45 = 71°

    And Finally, we solve for x.

    x = 180 - m∠BEC = 180 - 71 = 109° Answer//

    From your figure, we have

    <x=<DBC+45*

    =>

    <x=30*+34*+45*

    =>

    <x=109*

    The figure is fooling you, ignore the figure and look just at the data.

    The sum of inside degrees of any triangle is always = 180°

    The counter-adjacent angle is 180°minus inside degree.

    ABD = 180-34-30 = 116°

         X = absolute of (116-180-45) = 109°

    Some useful things to know: 

    Sum of angles in a triangle = 180 degrees

    Sum of angles on a line = 180 degrees

    180-30-34=116  left side of b.

    180-116=64  rt side of b

    180-64-45=71

    180-71=109=x

    Refer to the figure below. Label point E.

    A property of triangle: An exterior angle of a triangle is equal to the sum of the opposite interior angles.

    ∠DBC is an exterior angle of ΔDAB, and the two opposite interior angles are 34° and 30°.

    Then, ∠DBC = 34° + 30° = 64°

    x is an exterior angle of ΔEBC, and the two opposite interior angles are 64° (∠DBC) and 45°.

    Then, x = 64° + 45° = 109°

    Whoever drew the picture did a terrible job. It’s 109. 

    All interior angles of a triangle is 180 so you can find angle B in ABD. Then you can find angle B in BCX since a straight line is 180. To find angle X in BCX, you use the interior angles of a triangle. Once you find that, you subtract from 180 since a straight line is 180.

    In the given figure the value of 'x' is 45 + 74 = 109

    angle  DBC is 64° , thus x = 64° + 45° = 109°
