Answer:= I think it is 3.74
Answer:
x= 2
y= 7
z= 4
Step-by-step explanation:
Equation 1: x+y+z=13
Equation 2: x-z= -2
Equation 3: -2x+y=3
Add equation 2 and 1
(x+y+z)+(x-z)= 13 -2
2x+y= 11
Add this to equation 3
(-2x+y)+(2x+y)= 11+3
2y= 14
y= 7
Plug in y= 7 to equation 3
-2x+(7)= 3
-2x+7=3
-2x= -4
x= 2
Plug x=2 into equation 2
2-z= -2
4 = z
Answer:
The answer to your question is 10.7 units
Step-by-step explanation:
To solve this problem, just calculate the distance from the House to the Library, then the distance from the Library to the Post office and finally to the Post office to the house.
I hope this helps! Also, pls mark me as the brainliest!
AlSO IF YOU WANT THE STEP BY STEP EQUATION IT IS--->
dHL = \sqrt{(-2 + 3)^{2} + (-2 - 2)^{2}}
dHL = \sqrt{(1)^{2}+ (-4)^{2}}
dHL = \sqrt{17} = 4.1
dLP = \sqrt{(-2 -2)^{2} + (-2-2)^{2}}
dLP = \sqrt{(-4)^{2} + (-4)^{2}}
dLP = \sqrt{32} = 5.7
dPH = \sqrt{(2 + 3)^{2}+ (2 - 2)^{2}}
dPH = \sqrt{(5)^{2}+ (0)^{2}}
dPH = \sqrt{25}
dPH = 5
Minimum distance = 4.1 + 5.7 + 5
Minimum distance = 10.7

Answer:
cos(z) = .3846153846 and angle z = 67.38°
Step-by-step explanation:
Side UV is corresponding to side YX. Side VW is corresponding to side YZ. Side UW is corresponding to side XZ.
Starting with the first corresponding pair, we are told that side UV is 36, and that side YX is 3/5 of that. So side YX is

We are next told that side VW is 39, so side YZ is

In order to find the cos of angle z, we need the adjacent side, which is side XZ. Side XZ is 3/5 of side UW. Right now we don't know the length of side UW, so we find it using Pythagorean's Theorem:
and
so
UW = 15
Now we can say that side XZ is

The cos of an angle is the side adjacent to the angle (9) over the hypotenuse of the triangle (23.4) so our ratio is:

which divides to
cos(z) = .3846153846
If you need the value of the angle, use the inverse cosine function on your calculator in degree mode to find that
angle z = 67.38°
