Answer:
4:1
Step-by-step explanation:
x+20 : y+20 = 5 : 2
(x+20)/(y+20) = 5/2
2(x+20) = 5(y+20)
2x+40 = 5y+100
2x = 5y+60 (1)
x-5 : y-5 = 5:1
(x-5)/(y-5) = 5/1
x-5 = 5(y-5)
x-5 = 5y-25
x = 5y-20 (2)
Solve (1) & (2) simultaneously,
2(5y-20) = 5y+60
10y-40 = 5y+60
5y = 100
y = 20
x = 5y-20
x = 5(20)-20 = 100-20
x = 80
x:y
80:20

Answer:
Complementary angles, adjacent angles
Step-by-step explanation:
Which relationships describe angles 1 and 2?
Options: Complementary angles, vertical angles, supplementary angles, adjacent angles
Angles 1 and 2 are opposite to the 90° angle. So, the angles' relationship to that angles is a vertical angle, meaning that the two add up to 90°.
Complementary angles add up to 90°, so this option is correct.
Vertical angles are the pairs of opposite angles formed by two intersecting lines. Because the two angles do not follow this definition, this option is incorrect.
Supplementary angles add up to 180°. However, we know that the two add up to 90°, so this option is incorrect.
Adjacent angles are angles that are next to each other, so this option is correct.
I hope this helps! Feel free to ask any questions!
