B= 6 add 15 to 51 then divide by 11
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
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
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.
Pi=3.14. X=(3.14+3)/2. X=6.14/2. X=3.07 :)
