Step-by-step explanation:

We know that exterior angle of a triangle is equal to the sum of two opposite interior angle .So

<H + <G = <GFD

30° + 10x + 12° = 15x + 7 °

42° + 10x = 15x + 7°

42° - 7° = 15x -10x

5x = 35°

Therefore x = 7°

Now

<G = 10x + 12° = 10 * 7° + 12° = 70° + 12° = 82°

Answer:

Step-by-step explanation:

The idea here is to be able to write and then solve the equation needed for this. In words, this is what you are looking to solve: "The active ingredinet is 45% of the mass of the pill". Putting those words into an equation:

active ingredient = .45 (mass of pill). Since our active ingredient is 35 mg:

325 = .45m and divide by .45:

m = 722.2 mg
