Question

in the graphic below, the measure of angle abc is: triangle with right angle at d, angle at b (inside triangle) is 37 degrees, and b is on a line extending to c options: 143°, 90°, 127°, 53°

Explanation:

Step1: Identify supplementary angles

Angles on a straight line sum to \(180^\circ\). Angle \(ABD\) is \(37^\circ\), and angle \(ABC\) is supplementary to angle \(ABD\).

Step2: Calculate angle \(ABC\)

Using the supplementary angle formula: \( \angle ABC = 180^\circ - 37^\circ \)
\( \angle ABC = 143^\circ \)

Answer:

\(143^\circ\) (corresponding to the option with this value, e.g., if the first option is "143°", then the answer is the option with 143°)
