A whole triangle is total of 180°

as the two angles are same which is x, hence it is an isosceles triangle.

so using all the angles given,

46° + x° + x° = 180

by collecting all the like terms,

46° + 2x° = 180

GET RID of 46° on the left hand side
ADD of 46° on the right hand side

2x° = 180° - 46°
2x = 134°

now divide all with 2

2x÷2 = 134÷2
x° = 67°

therefore, the answer is x = 67°

1. what would the effect have been on the calculated formula weight ([9] above) of your unknown as compared to the true formula

kramer

If the solution is blue-green, this indicates that some copper is still present in the solution and that not all of it has precipitated. Expect it to be too low because you will have less mass.

With very few exceptions, all copper(I) (cuprous) compounds are diamagnetic and colorless. Cu2O, Cu2Cl2, and cuprous sulfide are a few of the significant commercial compounds of copper(I) (Cu2S).

The molar mass of the element copper is determined by looking at its average atomic mass, which is 63.55 AMU on the periodic table. Since it is also our molar mass, we will now put it in a different unit: grams over moles (63.55 gmol). That is copper's molar mass.

If the solution is blue-green, there is still copper in the solution and not all of it has precipitated. Because you will have less bulk, anticipate it to be too low.
