Answer:
1.
If two angles are supplementary, their sum is 180 degrees.
Check: 10 + 170 = 180
=> Maryam's claim is correct
If two angles are complementary, their sum is 90 degrees.
Check: 81 + 9 = 90
=> Ailia's claim is correct
2.
As the definition:
Vertical angles have sides that form two pairs of opposite rays.
Adjacent angles have a common side and don't overlap.
=> As provided pair of angles, they are adjacent pair of angles.
=> Ahmed's statement is wrong, Saalem's statement is correct.
Hope this helps!

Answer:
9/8
Step-by-step explanation:
The equation of a proportional relationship is ...
y = kx
The constant of proportionality, k, can be found from ...
k = y/x . . . . . above equation divided by x
Using the given points, we find the constant of proportionality to be ...
k = (3/4)/(2/3) = (3/4)(3/2) = 9/8
The constant of proportionality is 9/8.
The answer to your question is,
