Sample SOHCAHTOA Practice Problem with Solution
To illustrate, here's a typical problem you might find on a SOHCAHTOA worksheet with answers PDF:
Problem:
In a right triangle, the length of the side opposite angle A is 7 cm, and the hypotenuse is 25 cm. Find the value of sin A and cos A.
Solution:
Using sine:
sin A = Opposite / Hypotenuse = 7 / 25 = 0.28
Using cosine:
First, find the adjacent side using Pythagoras:
adjacent = √(hypotenuse² - opposite²) = √(25² - 7²) = √(625 - 49) = √576 = 24
Now, cos A = Adjacent / Hypotenuse = 24 / 25 = 0.96
Answer:
sin A = 0.28
cos A = 0.96
This type of problem, along with detailed solutions, is typically included in a SOHCAHTOA worksheet with answers PDF to help students learn effectively.
