Perimeter Calculation of a Geometric Shape

The video tutorial explains how to calculate the perimeter of a shape made from five right-angle triangles. It involves using trigonometry and Pythagoras theorem to find missing side lengths. The process includes identifying triangle properties, applying the sine function to find the hypotenuse, and using Pythagoras theorem to determine the short side. The final step is calculating the total perimeter and rounding the result to three significant figures.

What trigonometric function is used to find the hypotenuse when given an angle and the opposite side?

How do you ensure accuracy when using a calculator for these calculations?
