Answer:

100 degrees

Step-by-step explanation:

Angle 1 + Angle 2 = 180 degrees (linear pair theorem)

Angle 2 = Angle 6 (verticle angles theorem)

Thus, we can substitute the given values of angle one and angle six into the following equation:

Angle 1 + Angle 6 = 180

4x - 20 + 5x - 25 = 180

9x - 45 = 180

9x = 225

x = 25 degrees

Angle 2 = Angle 6

5x - 25 = Angle 6, so 5x - 25 = Angle 2

5(25) - 25 = Angle 2

100 degrees = Angle 2

Norma-Jean [14]

If the 4th lies opposite the 11th, then you know the 3rd lies opposite the 10th, the 2nd opposite the 9th, and the 1st opposite the 8th; meanwhile, in the reverse direction you'd find that the 5th lies opposite the 12th, the 6th opposite the 13th, and the 7th opposite the 14th. Move up one more bead and you're back at the 1st, which you already know lies opposite the 8th. Therefore there are 14 total beads.

The relationship between the percentage of frozen citrus crop, and the cost of box of oranges is an illustration of a linear function.

The linear equation of the function is: $g(P) =22.9P +7$ , while its inverse is: $g^{-1}(c) = \frac{c - 7}{22.9}$ .
The domain is from 0% to 100%, while the range is from 7 to 29.9
