Answer:

x=7

Step-by-step explanation:

The square indicates the angle is a right angle which equals 90°

5x+18+4x+9=90°

5x+4x+18+9=90°

9x+27=90°

9x=90°-27°

9x=63°

Divide both sides by 9

x=7.

Hope you're having a splendiferous day, ever willing to help...

Answer:

r = 6

Step-by-step explanation:

V(cyl) = π · r² · h

144π = π · r² · 4

144 = r² · 4

144 = r²

r = $\sqrt{144}$ ÷ $\sqrt{4}$

r = 12/2

r = 6

The surface area of the cube is 54 square feet. What is the length, in feet, of one edge of the cube?

Brut [27]

Answer:

3 ft

Step-by-step explanation:

A cube is made of 6 equal faces each of which is a square with the same side length. The surface area of the cube is the surface area of one side multiplied by 6. We know the surface area is 54 so divide this by 6.

54/6 = 9 ft^2

Since the surface must be a square, take the square root of 9 which is 3 ft. The length of one edge of the cube is 3 ft.

What is the value of x in the diagram?

Verizon [17]

2 lines parallel, and 2 triangles have a common angle
So the smaller Δ is similar to the bigger Δ (AA Similarity)
9:(4x-2)+9=12:(3x+2)+12
9:4x+7=12:3x+14
9(3x+14)=12(4x+7)
27x+126=48x+84
21x=42
x=2
So the answer is x=2
