Answer:
Solution tends to infinity
Step-by-step explanation:
Given the expression
(3x-2)/(x+3)-1=(3x-3)/(x+1)-2
This can also be expressed as;
(3x-2)/x+2 = 3x-3/x-1
3x-2/x+2 = 3(x-1)/x-1
3x-2/x+2 = 3
Cross multiply
3x-2 = 3(x+2)
3x-2 =3x+6
Collect like terms
3x-3x =6+3
0x = 9
x = 9/0
x = infinity
Hence the expression had no solution. It tends to infinity

A cone with a radius of 1-unit will be obtained by rotating the 3-D figure.
Answer:
3) 180°-50°=130°
4)90°-50°=40°
Step-by-step explanation:
5)angle DEC=50°(VERTICAL OPPOSITE ANGLE)
x=50°-15°=35°
6)Y+30°+50°=180°(linear pair)
Y=180°-80°
Y=100°
Let the height of the building be x. Let the initial distance of the ant from the building be y, then
tan 32 = x/y
y = x/tan 32 . . . . . . . . (1)
tan 22 = x/(y + 66)
y tan 22 + 66 tan 22 = x
y = (x - 66 tan 22)/tan 22 . . . . . . . . (2)
Equating (1) and (2), we have
x/tan 32 = (x - 66 tan 22)/tan 22
x tan 22 = x tan 32 - 66 tan 22 (tan 32)
x(tan 32 - tan 22) = 66 tan 22 (tan 32)
x = (66 tan 22 (tan 32))/(tan 32 - tan 22) = 66(0.4040)(0.6249)/(0.6249 - 0.4040) = 16.6626/0.2208 = 75.4
Therefore, the height of the building is 75.4 feet.
