The current temperature in Smalltown is 20 degrees Fahrenheit. This is 6 degrees less than twice the temperature that it was six hours ago. What was the temperature in Smalltown six hours ago? Give me the algebraic equation:​

d) by the cross product property, ab^2 = bc multiplied by ad

step-by-step explanation:

we are given

in the given triangle abc

angle a is 90° and segment ad is perpendicular to segment bc

we can see that

triangle(abc) and triangle(abd) are similar because they have common side and same angle (90 degree)

so, triangles(abc) and abd are similar

since, they are similar

so, the ratio of their sides must be equal

we get

now, we can cross multiply

and we get

so, this could be step to prove it

answer: 7
