Sohcahtoa Trigonometry Finding Sides Explained Gcse Maths Help Yout Sohcahtoa, or sine, cosine and tangent, or sin cos and tan. in this video we look at these three, and how and when to use them. of course, we are going to us. Maths genie limited is a company registered in england and wales with company number 14341280. registered office: 86 90 paul street, london, england, ec2a 4ne. maths revision video and notes on the topic of finding missing angles and lengths in right angled triangles using the trigonometric ratios sine, cosine and tangent. Show step. cos(36) = x 15 cos ( 36) = x 15. calculate the unknown side, rearranging if necessary. we can either solve the equation or use the sohcahtoa triangles. show step. x=12.1 (1.d.p) always check that the answer is sensible: as 12.1 is smaller than the 15 (the hypotenuse) it is a sensible answer. Find x. step 1 – label the triangle. we need to label the sides of the triangle with h (hypotenuse), o (opposite) and a (adjacent). h is the side opposite the right angle, o is the side opposite the angle and a is other side. step 2 – pick one of the sohcahtoa triangles. this is usually the step that trips people up.

Label the adjacent. decide which ratio from sohcahtoa – in this question we are going to use toa. so to calculate the angle: make sure the calculator is in degree mode (look for d symbol on your display) use the inverse trigonometric function (on a scientific calculator use the shift key to access) the angle x is: 39.80557109 degrees. Example 3 – worded sohcahtoa problem. quite often with trigonometry gcse maths revision questions you are presented with a worded problem and you need to sketch a diagram to help you solve the question. with enough practice of questions like these you will know that the question is one involving trigonometry.
