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
It means that the 2 equations are actually the same line. So, the system has a solution set of all the possible points on that line.
Formula for area of a rectangle is: A = l x w
A: Area
l: length
w: width
length of football field is 100 yards and width is 53.3 yards.
To find the area we need to multiply the length by width.
Area of football field = 100 x 53.3 = 5330 square yards (yards^2)
Answer:
- 
Step-by-step explanation:
=
( cross- multiply )
6x = 5y ( divide both sides by 6 )
x =
y
Then
← substitute x =
y into the expression
= 
= 
= 
=
× - 
= -
