A straight line is 180 degrees:
25x + 8 + 9x + 2 = 180
Combine like terms:
34x + 10 = 180
Subtract 10 from both sides:
34x = 170
Divide both sides by 34:
X = 5
Now solve the smaller angle:
9x + 2 = 9(5) + 2 = 45 + 2 = 47
They angle with the y is a vertical angle to 47 so needs to also equal 47:
7y + 5 = 47
Subtract 5 from both sides:
7y = 42
Divide both sides by 7:
Y = 6
Answer: x = 5, y = 6
Answer:
slope = -1/5
Step-by-step explanation:
The slope of a line between two points is ...
slope = (change in y)/(change in x)
= (-1 -0)/(5 -0) = -1/5
The slope of the line is -1/5.
Answer:
128.8cm^2
Step-by-step explanation:
area of circle with radius 6cm = π6^2
area of circle with radius 9cm = π9^2
shaded region is equal to π9^2 - π6^2
which is 41π
therefore the shaded region is = 128.8cm^2
