Answer:
Step-by-step explanation:
The numbers x, and y are the first three terms of an arithmetic progression.
For three consecutive terms, a, b and c of an arithmetic sequence:
The arithmetic mean,
Therefore:
The numbers x, and y are three consecutive terms of a geometric progression.
For three consecutive terms, a, b and c of a geometric sequence:
The geometric mean,
Therefore:
Substituting derived above, we have:
This is a quadratic equation which we can then solve for y.
Using a calculator, we obtain:
Therefore, the values of x and y are:
Answer:
1: The one vertical from 104° is 104°
2:The one near the corner is 20°
3: The two angles right next to 104° are 76°
Step-by-step explanation:
1: Vertical angle are always equal to each other.
2: All sides of the triangle must equal 180° in all. If you add 56° + 104° it equals 160°. Now subtract 180° - 160°. You get 20°.
3: All straight angles equal 180° in all. So, if you subtract 180° from 104° you will get 76°. And again, these two angles are vertical so they will both be 76°.
