- The image displays a right-angled triangle, indicated by a right angle symbol at the bottom corner.
- One acute angle within the triangle is labeled with the Greek letter theta, \(\theta\).
- The side opposite the angle theta is labeled with the variable \(y\).
- The longest side of the triangle, which is the hypotenuse relative to angle theta, is labeled with the variable \(h\).
- The mathematical relationship derived from the triangle is shown as \(\sin\theta = \frac{y}{h}\) and the inverse function is shown as \(\theta = \sin^{-1}\left(\frac{y}{h}\right)\).
