Question

find the measure of angles a, b, c, and d. 18° 11° a d b c progress: 0/4 part 1 of 4 m∠a=□°

Explanation:

Step1: Calculate the measure of angle \(a\)

Angle \(a\) is composed of two smaller angles of \(18^{\circ}\) and \(11^{\circ}\).
\(m\angle a=18^{\circ}+ 11^{\circ}\)

Answer:

\(29\)
