Answer:
When you reflect a point across the x-axis, the x-coordinate remains the same, but the y-coordinate is transformed into its opposite so just move it over to the opposite side
Step-by-step explanation:
100-10=90%
make proportion
x$-100%
36$-90%
x*90=100*36
x=3600/90
x=40$
Answer:
17.98
Step-by-step explanation:
Answer:
x = 33
Step-by-step explanation:
Sum of the interior angles of a 5-sided polygon = 540°
Therefore all the interior angles of the given polygon would all be equal to 540°.
Thus:
(4x - 25)° + (3x + 25)° + (2x - 3)° + (4x)° + (3x + 15)° = 540°
Solve for x
4x - 25 + 3x + 25 + 2x - 3 + 4x + 3x + 15 = 540
Combine like terms
4x + 3x + 2x + 4x + 3x - 25 + 25 - 3 + 15 = 540
16x + 12 = 540
16x = 540 - 12
16x = 528
Divide both sides by 16
x = 33
