Okay so i’m thing that the number that is gray means that, that is the measure of the whole angle. If I am correct then that means all you have to do is subtract the angle given from the whole angle to get x. Here is what I mean.
1. (117° - 94° = 23°) so x = 23°
2. These are vertical angles, which means that they will equal each other. So x = 148°.
3. (174° - 68° = 106°) so, x = 106°
4. (50° - 32° = 18°) so, x = 18°
5. Okay so since this is a straight line, it the bottom half does not matter. The straight line equals 180°. So here is you equation. (125° + x° + 30° = 180°. So let us add 125 & 30, which would get us 155°. Now let us subtract 155° from 180°, and that would get us, 25°. So x = 25°.
6. Once again these are vertical angles, meaning the will equal each other. So x = 113°.
7. So since x and 30° are on a straight line, x, 30° and the middle angle should equal 180°: Since the middle angle is vertical to 105°, the middle angle equals 105°. So now your equation is. 30° + 105° + x° = 180°. Now let us add 30° and 105° which would give us 135°. Now let us subtract 135° from 180° and that would give us, 45°, so therefore, x = 45°.
8. All you have to do is add all three angles. So your equation is: (30° + 15° + 89°) This will give you 134°. Therefore, x = 134°.
9. Once again these are vertical angles so x = 162°.
10. Okay so here your equation will be x = 90° + 29°. Imma tell you why.
Now the angle with the box in it, is obviously 90°. x is vertical from the whole angle on 90° and 29°, which means what? THEY SHOULD EQUAL EACH OTHER. So 90° + 29° = 119°. So x = 119°.
