Answer:

Step-by-step explanation:
Given the solution to an inequality
{x|x>2/3}
The solution set does not include
, therefore, it must be open at the left. Recall that we use a curvy bracket ( to denote openness at the left.
Since x is greater than
, the solution set contains all values of larger than
up till infinity. Since infinity is an arbitrarily large value, we also use an open bracket at the right.
Therefore, another way to represent the solution {x|x>2/3} is:

The correct option is C.
Answer:


Step-by-step explanation:
Given: See Attachment
Required
Determine the length of the legs
To do this, we apply Pythagoras theorem.

In this case:

Open Bracket

Solving using quadratic formula:

So:
or 
Since, x can't be negative, then:

One of the leg is:
