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.
