In an isosceles triangle, the angle between the altitude drawn to the base of the triangle and one leg of the triangle measures 16 less than one base angles of the triangle. find the measure of the vertex angle of this triangle

the law of definite proportions states samples of a compound will always contain the same proportion of elements by mass. in other words, a given compound will always contain the same elements in the same proportions by mass.the law of multiple proportions states when two elements combine with each other to form more than one compound, then the weights of one element that combine with a fixed weight of the other are in a ratio of small whole numbers.
