Question

what is the value of d? 61°

Explanation:

Step1: Recall angle - sum property

The two angles are adjacent and form a straight - line. The sum of adjacent angles on a straight - line is 180°.
So, \(d + 61^{\circ}=180^{\circ}\)

Step2: Solve for \(d\)

Subtract 61° from both sides of the equation: \(d=180^{\circ}-61^{\circ}\)
\(d = 119^{\circ}\)

Answer:

\(119\)
