Suppose that E and F are points on the number line. If EF=5 and F lies at -3, where could E be located?

There are two possible locations. E could be located in either -8 or 2.

Step-by-step explanation:

The number line is a one-dimensional graphing model for real numbers, in which each element is represented by points. Under this system, there are two directions:

- Left semiaxis that corresponds to negative real numbers.

- Right semiaxis that corresponds to positive real numbers.

Both semiaxis are divided by origin, which represents the real number zero.

Let E and F points on the number. If we know that and , there are two choices for the location of E. That is:

There are two possible locations. E could be located in either -8 or 2.

(sin 42)/31. = sinx)/37

sinx = 37 (sin42)/31

= 37× 0.66/31 = 0.787

x= 51.9

other angle opposite to y = 180-51.9-42

= 180- 93.9 =86.1

so

sin42)/31 = sin 86.1)/y

0.021 = 0.997 /y

y= 0.997/0.021 =47.47
