Answer:
Perpendicular(p)=21
base(b)=20
hypotenuse(h)=29
Step-by-step explanation:
Now by using the formula:
cos A=b/h
i.e 20 by 29
Answer: 2.5 ft.
Step-by-step explanation: We know that the wall is 10ft and each poster is 1 1/4 ft, so subtract both posters from the wall, 10-2.5 = 7.5, then divide 7.5 by 3 since we need 3 lengths, and we get 2.5ft. So for x, it would be 2.5ft.
x=2.5
Hope this helps!

Answer:
x = 8
y = -11
Step-by-step explanation:
In this question, we have to find out the value of "x" and "y".
Solve:
Lets solve for y first.
-2(3x + 4y = -20)
6x + 5y = -7
------------
-6x - 8y = 40
6x + 5y = -7
------------
-3y = 33
Divide both sides by -3
y = -11
We now know what the value of "y" is, now we must find the value of x. To do this, we would plug -11 to "y" in one of our equations.
Solve for x:
3x + 4y = -20
3x + 4(-11) = -20
3x - 44 = -20
Add 44 to both sides.
3x = 24
Divide both sides by 3
x = 8
Now we know that our answer are:
x = 8
y = -11
