i did it mentally lol
Step-by-step explanation:
The sum of the interior angles of a convex regular polygon is 180 times (n-2), where n is the number of sides. Since we already know the sum, we can write 3,960 = 180(n-2). If you solve for n in this equation, you will have the number of sides.
Hi there!
Since angles 3 and 7 are corresponding angles, they are also congruent. This means that angle 3 is equal to angle 7. Therefore, the correct answer is C, 120 degrees.
Answer:
2 ( n + 3 ) + 5 ( 2n + 4 ) = 62 *

Step-by-step explanation:
Given,
∠CBE ≅ ∠DBE ----> 1
∠CBE ≅ ∠BCA ----> 2
From 1 & 2,
∠BCA≅ ∠DBE ----> 3
∠DBE ≅ ∠BAC ----> 4
Reason,
Since BE II AC, corresponding angles are equal.
From 3 & 4,
∠BCA ≅ ∠BAC
BC is opposite to ∠BCA
AB is opposite to ∠ABC
Side opposite to congruent angles are always congruent.
Therefore,
AB ≅ BC
Hence proved.
