Find the tan of the base angle of an isosceles triangle if the equal sides are 82cm long and the other side is 36cm long?

An isosceles triangle can be considered as being two right angled triangles joined together and if we divide the base by 2 this gives us two adjacent sides of 18cm. By rearranging Pythagoras' Theorem we can calculate that the opposite side or perpendicular height of the triangle is 80cm: Pythagoras' Theorem: 822-182 = 6400. The square root 6400 is 80. Tangent = opposite/adjacent 77.31961651o = 80/18 Alternatively the Cosine ratio can be used: Cosine = adjacent/hypotenuse 77.31961651o = 18/82 Or even the Sine ratio: Sine = opposite/hypotenuse 77.31951616o = 80/82 Therefore the isosceles triangle has two equal base angles of 77.32 degrees correct to two decimal places.
