Answer:
x = 71
Step-by-step explanation:
Given the triangle in red, we can find the unknown angle since the sum of the angles of a triangle are 180. Call the unknown angle GHI
B+ D+ GHI = 180
31+ 40 + GHI = 180
71 + GHI = 180
GHI = 180 -71
GHI = 109
We know that GHI + x = 180 since it forms a straight line
GHI + x =180
109 + x = 180
x = 180-109
x = 71
Answer:
-2=9
0=-5
1=-3
2=-1
5=5
Step-by-step explanation:
Replace 'x' with the number corresponding to the side of the table.
Ex. f(-2)=2(-2)-5
The area of one face would he h^2.
There are 6 faces, so the total surface area would be h^2 x 6
Replace total surface area with 2.16, so you now have:
2.16 = h^2 x 6
Now we can solve for h.
Divide both sides by 6:
h^2 = 2.16/6
Take the square root of both sides:
h = √2.16/6
The answer is A.
Answer:
Step-by-step explanation:
VZ = 44-27.5 = 16.5
ZY/VY = ⅝
WX = ⅝ of VX
VX = 36×8/5 = 57.6
VW = VX - WX = 21.6 units
