Figure VWYX is a kite.<br><br> What is the value of x?

Alecsey [184]

Answer:

$x=6\°$

Step-by-step explanation:

we know that

The sum of the internal angles of a kite is equal to $360\°$

In this problem we have

$90\°+90\°+(18x-2)\°+(12x+2)\°=360\°$

$(18x-2)\°+(12x+2)\°=360\°-180\°$

$30x=180\°$

$x=6\°$

Answer:

$\boxed{\text{15.8 cords}}$

Step-by-step explanation:

Step 1. Calculate the volume of the room

V = lwh = 5 yd × 5 yd × 3 yd = 75 yd³

Step 2. Convert cubic yards to cubic feet

3 ft = 1 yd

$V = \text{75 yd}^{3} \times \left(\dfrac{\text{3 ft}}{\text{1 yd}} \right)^{3} = \text{2025 ft}^{3}$

Step 3. Convert cubic feet to cords

128 ft³ = 1 cord

$V = \text{2025 ft}^{3} \times \dfrac{\text{1 cord}}{\text{ 128 ft}^{3}} = \textbf{15.8 cords}\\\\\text{You could fit }\boxed{\textbf{15.8 cords}} \text{ of wood into the room.}$
