Answer:

[see below]

Step-by-step explanation:

An equation is a mathematical statement that states that two expressions are equal. Equations have an equal sign.

An inequality is a mathematical statement that states that two expressions are greater than, less than, greater than or equal to, or less than or equal to.

An expression is a combination of mathematical symbols that show the value of something. It does not have any inequality sign nor an equal sign.

$\frac{7}{x}< 6$ is an inequality. It has a less than sign.

3 - 2 is an expression. It does not have any inequality sign nor an equal sign.

$4^2+8=9$ is an equation. It includes an equal sign.

Answer:

$9$

Step-by-step explanation:

As per the problem, the given triangle is a right triangle. This is signified by the box around one of its angles, this box states that the angle it is surrounding is a right angle.

Since it is a right triangle, one can use the Pythagorean theorem to solve this problem. The Pythagorean theorem states that; ( $a^2 + b^2 = c^2$ ), where ( $a$ ) and ( $b$ ) are the legs of the right triangle, or the sides adjacent to the right angle. ( $c$ ) is the hypotenuse or the side opposite the right angle.
