Vika [28.1K]

Step-by-step explanation:

Assuming the readable scores are:

100, 82, 95, __ , 90, 81, 75, 83, __

We know the mean (or average) is 85, so:

85 = (100 + 82 + 95 + x + 90 + 81 + 75 + 83 + y) / 9

765 = 606 + x + y

159 = x + y

We know the lowest score is 75, so x and y must be at least 76.  Possible answers are:

76 and 83

77 and 82

78 and 81

79 and 80

80 and 79

81 and 78

82 and 77

83 and 76

If sine of x equals square root of 2 over 2, what is cos(x) and tan(x)? Explain your steps in complete sentences.
kolbaska11 [484]
Sin x =  square root (2) / 2

In order for us to get for cos x and tan x, first we need to know what 
Hypotenuse, Adjacent, and Opposite sides.

sin x = opposite / hypotenuse.

adjacent = square root (hypotenuse^2 - opposite^2)
adjacent = square root (2^2 - square root(2)^2)
adjacent = square root (4 - 2)
adjacent = square root (2)

cos x = adjacent / hypotenuse
tan x = opposite / adjacent..

cos x = square root (2) / 2
tan x = square root (2) / <span>square root (2)  = 1

So, </span>cos x = square root (2) / 2 and tan x<span> = 1</span>
