Perimeter = 2(10+20) = 60feet
60ft fencing material is needed
By using trigonometric relations, we will see that:
AC = 15.6 in
AB = 8.4 in.

How to get the measures of the other two sides of the right triangle?</h3>
Here we have the right triangle where:
B = 90°
C = 40°
BC = 10 in.
Notice that is the adjacent cathetus to the angle C, then we can use the two relations:
- sin(a) = (adjacent cathetus)/(hypotenuse).
- tan(a) = (opposite cathetus)/(adjacent cathetus).
Where:
- hypotenuse = AC
- opposite cathetus = AB.
Then we will have:
sin(40°) = 10in/AC.
AC = 10in/sin(40°) = 15.6 in
tan(40°) = AB/10in
tan(40°)*10in = AB = 8.4 in.
So we can conclude that for the given right triangle we have:
AC = 15.6 in
AB = 8.4 in.

Yes that is correct because for the problem is 56,154 so if you round that will get you 56,000
Answer:
x<=-2
Step-by-step explanation:
-6<10-4x>=18
subtract 10
-16<-4x>=18
Divide by -4
x<=-2
