1. C. Concave pentagon
2. A. 1620°
b/c (11 - 2) × 180 = 1620
3. B. 165°
b/c (24 - 2) × 180 ÷ 24 = 165
4. A. 160°
b/c (18 - 2) × 180 ÷ 18 = 160
Answer:
Equation: 243+x=327
Answer to the equation: x=84
Step-by-step explanation:
First, subtract 243 from both sides of the equation, which would leave you with x=84, which is your answer.
I hope this helps! :)
Answer:
EBC and ABE, as well as ABD and ABE
Step-by-step explanation:
Supplementary angles form an 180 degree angle. In other words, they form a straight line.
EBA and DBC are each greater than 90 degrees and are vertical angles, not supplementary angles.
EBC and ABE form a straight line. So they are supplementary angles.
ABD and ABE form a straight line. So they are also supplementary angles.
CBE and ABD are each less than 90 degrees and are vertical angles, not supplementary angles.
So, EBC and ABE, as well as ABD and ABE are the correct choices.
