Answer: In geometry, a pentagon is a five-sided polygon with five straight sides and five interior angles that sum up to
540
°
. A pentagon shape is a plane figure, or flat (two-dimensional) 5-sided geometric shape.
Properties of a Pentagon
1. Pentagons have five straight sides
2. Pentagons have five interior angles, which sum to
540
°
3. The five sides do not intersect
Step-by-step explanation: Hello, I have only told you the properties on how to tell if it's a pentagon, please explain or show some type of image if you still need help!
Answer:
True.
Step-by-step explanation:
The sides are legs and that's what makes it isosceles.
well, let's keep in mind that the SAS postulate, so if one Side and the Angle next to it and the following Side after the angle are equal on both triangles, both triangles are congruent. Now, we have the angle 30° with sides and 9 and 2x and sides 9 and x + 4, well, the 9's are equal, dohh, you know, if only the 2x = x + 4, we'd be golden
the answer is
Remove unnecessary parentheses.<span><span>5+2x+16x−56</span><span>5+2x+16x-56</span></span>
Subtract <span>5656</span> from <span>55</span> to get <span><span>−51</span><span>-51</span></span>.<span><span>2x+16x−51</span><span>2x+16x-51</span></span>
Add <span><span>2x</span><span>2x</span></span> and <span><span>16x</span><span>16x</span></span> to get <span><span>18x</span><span>18x</span></span>.<span>18x−<span>51</span></span>
