I learned how to find the other sides of a right triangle using the Pythagoras theory with only one side and angle this can be done by first finding the trigonometric ratio that the side we have and the other one we don’t are both in. Then cross multiply the ratio and the angle with the side we don’t have as a variable and the side in their ratio form. An example of this being done was if we had the adjacent of angle 30 and the angle is 40 to find the hypotenuse we know that they are both in cosine ratio with the adjacent divided by the hypotenuse we write it as 30/A then we can cross multiple by the angle 40 cosine this equation equals (Cos 40 = 30/h) then the hypotenuse is 39.2(nearest tenth). Another example of this being done is if we had the hypotenuse is 20 and the angle we have is 16 then we want to find the adjacent side we can notice that they are both in cosine ratio which we write as x/20 then we cross multiply that by cos 16 which equals 19.2 so 19.2 is the adjacent side.
