Answer:
see explanation
Step-by-step explanation:
Since the marked angles are congruent, let them be x
(6)
The sum of the interior angles of a quadrilateral = 360°
Sum the angles and equate to 360
x + x + 120 + 90 = 360
2x + 210 = 360 ( subtract 210 from both sides )
2x = 150 ( divide both sides by 2 )
x = 75
Then ∠ X = ∠ Y = 75°

(7)
The sum of the interior angles of a hexagon = 720°
Sum the angles and equate to 720
x + x + 108 + 103 + 149 + 90 = 720
2x + 450 = 720 ( subtract 450 from both sides )
2x = 270 ( divide both sides by 2 )
x = 135
Then ∠ X = ∠ Y = 135°
Answer: y=3x -10
slope : 3 y-int : -10
Step-by-step explanation: I believe this is the answer
9. The experimental probability that it will rain on any given day in Houston Texas is about 15%.
Thus, out of 365 days, 15% of that are the predicted days the it will rain in the Place.
=> 365 days is the total number of days in a year
=> 15% is the predicted days to rain
=> 365 * .15 = 54.75
Since this is a decimal number, let’s round this off to 55 days.
Why 55 because the value of tenths is more than 5.
Line j is negative and line k is postive so you combine hem in like terms to solve them
