4. What is the measure of each interior angle of a regular 28-gon?

melomori [17]

Step-by-step explanation:

Measure of each interior angle of 28 sided polygon

$\frac{(28 - 2) \times 180 \degree}{28} \\ \\ = \frac{26 \times 180 \degree }{28} \\ \\ = \frac{4680 \degree }{28} \\ \\ = 167.14\degree \\$

The sum of an infinite geometric series is 1,280, while the first term of the series is 160. What is the common ratio of the ser

Arlecino [84]

The sum is 160/(1-r)=1280 where r is the common ratio,
1/(1-r)=1280/160=8
Inverting we get 1-r=1/8, r=7/8.

Pls help I will mark brainliest.

Vikentia [17]

Step-by-step explanation:

If angle 1 is 121 degrees, then angle 7 is 59 degrees. (same side exterior angles)

If angle 8 is 103 degrees, then angle 4 equals 103 degrees (corresponding angles) and angle 3 is 77 degrees. (to angle 4 supplementary angles)

If angle 5 is 116 degrees, then angle 3 is 64 degrees. (same side interior angles)
