Answer:
17.7
Step-by-step explanation:
This figure is a pentagon - a shape with 5 sides. In a pentagon, the figure's angles add to 540.
100 + 7x-4 + 3x + 23 + 9x - 6 + 90 = 540
190 +19x + 13 = 540
203 + 19x = 540
19x = 337
x = 17.7
Answer:
3.124 kilometers
Step-by-step explanation:
The answer is C, because there are two different numbers correlated to the same number on the Y side. The table does not represent a function.
Answer:
y= -4
Step-by-step explanation:
simplify both sides of the equasion
add 2y to both sides
add three to both sides
and your answer is y= -4
Wouldn’t you add both of the equations together and set them equal to 180 and whatever you get for x just plug back in to find the values of the angles??
