Answer:
x = 14.5
Step-by-step explanation:
The diagonals of a rhombus are at right angle to each other, then
∠ BOA = 90° , so
6x + 3 = 90 ( subtract 3 from both sides )
6x = 87 ( divide both sides by 6 )
x = 14.5
Answer:
First, find the area of the surface of the shed. Two walls will have an area of 14 x 8 and two walls will have an area of 18 x 10. We get the equation 2(14x8) + 2(10x8) = 224 + 160 = 384 square feet
Next, divide the square footage of the shed's surface by 250 to find how many gallons of paint are needed. 384/250 = 1.54 gallons of paint (rounded to the nearest hundredth)
For the triangle questions, remember that the area of a triangle is
