Answer:

10

Step-by-step explanation:

In a polygon

interior angle + interior angle = 180°, thus

exterior angle = 180° - 144° = 36°

The sum of the exterior angles in a polygon = 360°, thus

number of sides = \frac{360}{36} = 10

Answer:

10 sides

Step-by-step explanation:

A decagon is a 10-sided polygon, with 10 interior angles, and 10 vertices which is where the sides meet. A regular decagon has 10 equal-length sides and equal-measure interior angles. Each angle measures 144° and they all add up to 1,440°.

What is -0.8x - 6 < -10
puteri [66]
Solving an equation is simply like solving an equation. For this problem, you must add 6 on both sides to get -0.8x alone. -10 + 6 would equal -4. Therefore, the inequality would look like this: -0.8x < -4 
Now you have to divide -0.8 on both sides to have x alone. Since you are dividing a negative to the other side, the sign flips to >. When you divide -0.8 to -4, the answer would be 5. So therefore, the answer is: x > 5 
In order to check this, you must plug in 5 into the x. -0.8 times 5 would equal -4. -4 - 6 would equal -10. -10 is the same as the other side. (-10 < -10) That means the answer would be correct. Hope this helps; cheers, mimiisawesome5
