T= 3vs-4ws+5vw; solve for v
MrRa [10]
T=3vs-4ws+5vw
add 4ws to both sides
T+4ws=3vs+5vw
factor out v
T+4ws=v(3s+5w)
divide both sides by 3s+5s
\frac{T+4ws}{3s+5s}=v

Find the value of x.
zepelin [54]

Answer:

Step-by-step explanation:

Using the Z theorem, the upper  angle on the right = 60 degrees.

The angle which includes 3x is 120  because this is a parallelogram and consecutive angles must add to 180. So 180 - 60 = 120

The angle above the 3x is 120 - 3x

120 - 3x + 90 + 2x = 180 These angles make a straight line line. Combine.

210 - x = 180                    Subtract 210 from both sides.

- x = 180 - 210                  Combine

-x = - 30                           Multiply both sides by - 1

x = 30

What is the surface area of the square pyramid?<br><br><br><br> Enter your answer in the box.
Vlad1618 [11]

Answer:

240 inches squared.

Step-by-step explanation:

To find the surface area, find the area of each triangle and the square. Then add all the areas together.

Triangle - A = 1/2bh where b = 8 and h = 11. So the area of 1 triangle is A = 1/2*8*11 = 44. Since there are 4 triangles then 4*44 = 176 inches squared.

Square - A = s^2 where s = 8. So the area of the square is A = 2^2 = 8^2 = 64.

So all the areas add together to 176 + 64 = 240.
