A is continuous
B is discrete
C is not a function
S is a function
Answer:
See answers below
Step-by-step explanation:
Since both trinagles asre similar hence the ratio of the similar sides are equal.
From both triangles;
y + 7 = 3y - 7
y - 3y = -7-7
-2y = -14
y = 14/2
y = 7
FE = 3y - 17
FE = 3(7) - 17
FE = 21 - 17
FE = 4
AB = y'+7
AB = 7 + 7
AB = 14
Similarly
3x+20 = 5x - 80
3x -5x = -80-20
-2x = -100
x = 100/2
x = 50
<A = 3x + 20
<A = 3(50) + 20
<A = 150 + 20
<A = 170degrees
Hence x= 50 and y = 7

Let the width of the field = x.
Then the length = 4x
Now the perimeter = 2 * length + 2 * width, so we have the equation:-
2*4x + 2x = 340
8x + 2x = 340
10x = 340
x = 34 yards = width
4x = length = 136
Answer: the width is 34 yards and length is 136 yards.
