Step-by-step explanation:

You have to use the Law of Cosines here to find angle R.  Namely,

Filling in:

and

and

and

so

Use the 2nd button and then the cos button to find the angle that has a cos of that decimal.  You should get, as long as you are in degree mode, that angle R = 31.4°

since proposition states that a number is greater than 25, if is true then the number must actually be greater than 25.

this implies that all possible options, except 24, can be accepted

in the math equation 8 x 7 = 56, the 8 and the 7 are both factors of 56, since in this lesson we will use square tiles to figure out the factors of a whole find as many different arrays as you can, but follow one important rule: all the rows must have the i can make two rows of nine, so 2 and 9 are both factors of 18.
