The problem asks to identify the hypotenuse, the opposite side, and the adjacent side to the angle $\theta$ in each of the given right triangles.

1. Problem Description

The problem asks to identify the hypotenuse, the opposite side, and the adjacent side to the angle $\theta$ in each of the given right triangles.

2. Solution Steps

Recall the definitions:

- Hypotenuse: The side opposite the right angle in a right triangle. It is always the longest side.

- Opposite side: The side opposite to the angle $\theta$.

- Adjacent side: The side adjacent to the angle $\theta$ that is not the hypotenuse.

- Opposite: $b$

- Adjacent: $a$

(b)

- Hypotenuse: $c$

- Opposite: $a$

- Adjacent: $b$

(c)

- Hypotenuse: $c$

- Opposite: $a$

- Adjacent: $b$

(d)

- Hypotenuse: $c$

- Opposite: $a$

- Adjacent: $b$

(e)

- Hypotenuse: $x$

- Opposite: $y$

- Adjacent: $z$

(f)

- Hypotenuse: $x$

- Opposite: $y$

- Adjacent: $z$

(g)

- Hypotenuse: $u$

- Opposite: $s$

- Adjacent: $t$

(h)

- Hypotenuse: $u$

- Opposite: $t$

- Adjacent: $s$

(i)

- Hypotenuse: $b$

- Opposite: $c$

- Adjacent: $a$

(j)

- Hypotenuse: $b$

- Opposite: $c$

(e) Hypotenuse: $x$, Opposite: $y$, Adjacent: $z$

(f) Hypotenuse: $x$, Opposite: $y$, Adjacent: $z$

(g) Hypotenuse: $u$, Opposite: $s$, Adjacent: $t$

(h) Hypotenuse: $u$, Opposite: $t$, Adjacent: $s$

(i) Hypotenuse: $b$, Opposite: $c$, Adjacent: $a$

(j) Hypotenuse: $b$, Opposite: $c$, Adjacent: $a$
