Step-by-step explanation:
The temperature was originally 2 degrees because if you draw a number line and put a 0 in the middle of the positive numbers and the negative numbers ( - 8 - 7 - 6 -5 - 4 0 1 2 3 4 5 6 7 8) - example. Put the positive and negative numbers on different sides of the 0 and go left from the positive numbers from 2 and count 6 skips down to - 4. So 2 would be your answer.
The length of PR is 4.4 units.
Explanation:
It is given that the length of the hypotenuse is 10 units.
Also, the angle of R is 64°
To find the length of PR, we shall use the cosine formula,

Here,
, adj = PR and hyp = 10
Substituting these values in the formula, we get,

Multiplying both sides by 10, we get,

Substituting the value for cos 64, we get,

Multiplying, we have,

Rounding off, we get,

Thus, the length of PR is 4.4 units.
