Answer:
x=12.6
Step-by-step explanation:
5x -9 / 7
5x= -9x7
5x= -63
x= -63/5 = -12.6
x= -12.6
A=bh/2, that is area is equal to half of the product of the base and height, so in this case:
A=(1/2)*10*24
Answer: 113, 57, and 66
Step-by-step explanation:
The sum of all of the interior angles can be found using the formula S = (n - 2)*180. It is also possible to calculate the measure of each angle if the polygon is regular by dividing the sum by the number of sides.

Answer:
Step-by-step explanation:
1. Rotate 90° counterclockwise about the origin and then translate 5 units left.

- Incorrect, this ends up in the first quadrant, additional translation is required
3. Rotate 180° about the origin.
- Incorrect, additional translation is required followed by rotation.
4. Rotate 90° clockwise about the origin and then translate 1 unit right and 5 units up.
