Ryan is 5 feet tall. his shadow 9 feet long and the shadow of a building is 36 feet long. how tall is the building?

x=20

Step-by-step explanation:

Step 1: Cross-multiply.

5/9=x/36

(5)*(36)=x*(9)

180=9x

Step 2: Flip the equation.

9x=180

Step 3: Divide both sides by 9.

9x=180

9x/9=180/9

x=20

answer: i dont know but if you try hard you will get it right : )

step-by-step explanation:

18 units²

step-by-step explanation:

first let's find altitude bd using the distance formula

d = √((y₂ - y₁)² + (x₂ - x₁)²)

bd = √((0 - -3)² + (0 - 3)²)

bd = √18

given the placement of points a and c, we can denote that point d bisects segment ac.

we will call ac the base.

using the distance formula

ac = √((0 - 6)² + (-6 - 0)²)

ac = √72

knowing our base and our height, we can plug these into our triangle area formula

area = (b * h)/2

area = (√18 * √72) / 2

area = (√1296) / 2

area = 36 / 2

area = 18 units²
