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!

Do solve this you use PEMDAS. This stands for:
Parenthesis
Exponents
Multiplication
Division
Addition
Subtraction
Because there are no parentheses or exponents in this equation, we go straight to the division.
1) 8 divided by 4 equals two so we rewrite the equation. 5+6 x 2 - 2 + 7.
2) Next in order of pemdas is multiplication. Yes I know that in pemdas multiplication does come before division but it doesn’t matter in this problem which you do first. So now we do 6 x2 =12. We then rewrite the equation 5+12-2+7.
3) lastly, addition and subtraction are grouped together and you can just do it in order of the problem. So we do 5+12=17. 17-2=15. And 15+7=22.
So the final answer is: 22
The composition of 2 functions is B
Answer:
c
Step-by-step explanation:
Two sum of any two side lengths of a triangle will always be greater than the length of the remaining side
a doesn't work because 8+12=20 and 20 is not greater than 20
b doesn't work because 4+5=9 and 9<10
d doesn't work because 6+6=12 and 12 is not greater than 12
c is the only option where you can take any two sides, add them, and the sum will be greater than the remaining side.
For example, for c,
6+8=14, and 14>10
8+10=18, and 18>6
10+6=16, and 16>8
