Question

explore the properties of angles and arcs formed by two intersecting secants.
√ 1. find the difference of arc measures
m⌢ac - m⌢de = 56°

1. multiply the angle measure by 2.

2(m∠abc) =
m∠abc = 28°
m⌢ac = 80°
m⌢de = 24°

Explanation:

Step1: Identify given angle measure

$m\angle ABC = 28^{\circ}$

Step2: Multiply the angle measure by 2

$2\times28^{\circ}=56^{\circ}$

Answer:

$56$
