Question

1. The measure of an interior angle of a regular hexagon to the measure of an interior angle of an a regular decagon

2. The sum of the exterior angles (one angle at each vertex) of a regular pentagon to the sum of the exterior angles(one angle at each vertex) of a regular dodecagon
3. The measure of ∠A to the measure of ∠B, given that ∠A and ∠B are vertical angle
4. HT to UN, given that ▰HUNT is a parallelogram

help plsss asapppp

Answer 1

The sum of the exterior angles of a decagon is 360°

The sum of the exterior angles in an any polygon = 360°

Alternate method:

Each exterior angle in a polygon : 360 ÷ number of sides

Here, decagon has 10 sides.

Then, each exterior angle: 360 ÷ 10 = 36°

Then all 10 sides together has : 36° x 10 = 360°
