2x+6=45
2x=39
x=19.5
i hope that's helpfull......... is it?
Answer:
$109.71
Step-by-step explanation:
first we find the perimeter
=2(280+200)
=2×480
=960m
now we multiply it by 4 as he wants it 4 times around
960×4
3840
now we find the fencing cost
since 35 per meter we divide it by 35
3840/35
=$<u>109.71</u>
This is a right angle triangle problem
drawing a vertical line at from the point where the ramp touches the car park leaves a right angle triangle with the
opposite being 2m
hypothenus being 10m
adjacent unknown
we could use sine
SineO equal to opposite over hypothenus
SineO equal to 2/10
SineO equal to 0.2
O equal to Sine^1(0.2)
O equal to 11 .5
The angle between the ramp and the horizontal is 11.5 degrees
Answer:
x=25
Step-by-step explanation:
5x-5+ 2x+10 =180
2x-5x = 10+5
3x= 15
x=5
5(5)-5+ 2(5) +10 =180
