Tree Height sent us to triangles! Pulled out the protractor n worked the angles. Then we got a foretaste of sin cos tag! Girls took the trip but I enjoyed it! Triangle showing Opposite, Adjacent and Hypotenuse
The equation can be written in parametric form using the trigonometric functions sine and cosine as where t is a parametric variable in the range 0 to interpreted geometrically as the angle that the ray from (a, b) to (x, y) makes with the x-axis.
Example Problem : In a right triangle, the base is 6 cm and the perpendicular is 8 cm. Find the length of the hypotenuse of the triangle? Solution: By using Pythagoras Theorem, + = 62 + 82 = 36 + 64 h = 10 Hypotenuse is 10 cm
