Answer:
1
Step-by-step explanation:
tan 45 = cos 45 / sin 45.
Since sin(x)=cos(90-x), cos 45 = sin 45, so tan 45 = 1

Answer:2boys for five studenrs so 2/5 and for girls 3/5 so response is 3/5
Step-by-step explanation:
Substituting y=x-6 into the equation,
3x + 2(x-6) = 3x + 2x - 12 = 5x - 12
5x - 12 = 8
5x = 20
x = 4
Answer:
A
Step-by-step explanation:
We assume this playground is a rectangle. The area of a rectangle is of the form: A = lw, where l is the length and w is the width.
Here, the length is l = x and the width is w = x + 3. So, plug these in:
A = lw
A = x(x + 3)
Expand this out:
A = x² + 3x
The answer is thus A.
