Answer:

Step-by-step explanation:

The sum of the interior angles of a polygon is

sum = 180° (n - 2) ← n is the number of sides

Here the sum is 2520, thus

180° (n - 2) = 2520 ( divide both sides by 180 )

n - 2 = 14 ( add 2 to both sides )

n = 16

The polygon has 16 sides.

Lines a and b are parallel. What is the measure of angle s?

Arte-miy333 [17]

Answer:

Step-by-step explanation:

t = 158 Corresponding angles

t + s = 180 They are supplementary angles

158 + s = 180 Subtract 158 from both sides

s = 180 - 158

s = 22

As a note, all angles in this situation are either 158 or 22.

Naya [18.7K]

Answer:

See explanation for answers

Step-by-step explanation:

Reason 1) Given from the problem statement(because it says that B is the midpoint of AC)

Reason 2) Because B is the midpoint of AC

Reason 3) Given frome the problem statement(because it says that AB/cong CD)

Reason 4) Because two lines congruent to each other have the same length

Reason 5(You didn't explain well)) BC=AB=CD, so BC=CD(Specific reason: Transitivity of equality)

And we're done!
