Answer:
i. sin(C) = 
ii. tan(C) = 
iii. sin(B) = 
Step-by-step explanation:
Given a right angled triangle ABC, with a right angle at A.
<ABC = 
<BCA = 
AC = 9 = 1
CB = 18 = 2
Applying Pythagoras theorem to ΔABC, we have;
AB = 
= 
=
Thus applying the trigonometric ratios, it would be observed that;
i. sin(C) =
ii. tan(C) =
iii. sin(B) =
Answer:
$20-$14=$6
Step-by-step explanation:
this is correct because if you give the $20 to them and the toy costs $14 then you subtract that from the amount you gave them then whatever is left is how much you get back.

If you want to use integer tiles to find the product of 2(-5), think of it as you having 2 groups of 5 negative tiles, that is
-1 -1
-1 -1
-1 -1
-1 -1
-1 -1
Think of it as you having each of the -1 inside it's distinct tile. Now adding up these tiles you have -10.
Therefore 2(-5) is -10 using integer tiles.
If we are to use the number line, first draw your number line, then think of it as jumping twice while each jump is -5 big.
So the first jump from 0 will land on -5 and the second jump will land on -10 and that is the required answer using the number line.
