If sin(x) = squareroot 2 over 2 what is cos(x) and tan(x)

Bumek [7]

Answer:

cos(x) = square root 2 over 2; tan(x) = 1

Step-by-step explanation:

$\frac{\sqrt{2} }{2}$

was, before it was rationalized,

$\frac{1}{\sqrt{2} }$

Therefore,

$sin(x)=\frac{1}{\sqrt{2} }$

The side opposite the reference angle measures 1, the hypotenuse measures square root 2. That makes the reference angle a 45 degree angle. From there we can determine that the side adjacent to the reference angle also has a measure of 1. Therefore,

$cos(x)=\frac{1}{\sqrt{2} }=\frac{\sqrt{2} }{2}$ and

since tangent is side opposite (1) over side adjacent (1),

tan(x) = 1

The number of students at Marita’s school decreased to 98% of last year’s number. Currently, there are 1,170 students. How many

77julia77 [94]

Answer:

1194 students last year

Step-by-step explanation:

The problem statement tells us ...

98% × (students last year) = 1170

Dividing by 98%, we get ...

1170/0.98 = (students last year) = 1193.88 ≈ 1194

___

<em>Check</em>

1170/1194 = 0.979899... ≈ 0.98 = 98%
