A $1,628 g$ sample of a hydrate magnesium iodide is heated until its mass is reduced to $1,072 g$ and all water has been removed. What is the formula of the hydrate? (MgI $\cdot x_{ H _2 O }$ )

The sum of all angles of a triangle is 180 grades (or Pi radians).
The angles are in ratio 2:3:7, this means that by naming an angle X we will have:
2 X+ 3 X + 7*X= 180
so, 12*X =180 => X=15
The first angle is 2* X= 30 grades The second angle is 3 X= 45 grades The last angle is 7 X=105 grades

The angles of the triangle with a ratio of 2:3:7 are 30 degrees, 45 degrees, and 105 degrees. The total of these angles equals 180 degrees, satisfying the angle sum property of triangles. Each angle corresponds to a multiple of 15, which is derived from the given ratio.
