Mathematics
2 answers:
Wittaler [7]3 years ago

Answer:

angle 1 = 45⁰ (alternate angle)

angle 2 = 180⁰ - 45⁰ = 135⁰ (straight line angle )

<h3>Answers:</h3><h3>Angle 1 = 45 degrees</h3><h3>Angle 2 = 135 degrees</h3>

Explanations:

Angle 1 is 45 degrees because it pairs with the 45 degree angle shown. These two angles are congruent due to the alternate interior angle theorem. This only works when lines a and b are parallel.

Angle 2 is 135 degrees because it must add to angle 1 to result in 180 degrees. This is the same side interior angle theorem. Also, note that the original 45 degree angle is adjacent to angle 2, and these two angles form a straight line, so this is another way to see that 45+135 = 180.

The measure of an interior angle of a regular polygon is 120°. What is the measure of each exterior angle? The polygon has how m
Sunny_sXe [5.5K]

Answer:

60°, arms 6

Step-by-step explanation:

let the total arms = n

total generated angles in a regular polygon is = (n-2)×180

now,

(n-2)×180 = 120 n

or, 180n - 360 =120n

or, 60n = 360

or, n = 6
