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:
12/5 or 2⅖
Step-by-step explanation:
2x/3 = 8/5
2x = 3 × 8/5
2x = 24/5
x = 24/5 ÷ 2
x = 12/5
Or 2⅖
Area of a rectangle = length x width
3/4 x 5/12 = 15/48
15/48 = 5/16
The area of Kurt's maze is 5/16 square feet.
