The sum of two numbers is 180. If one number is 40% more than the other, find the numbers

75, 105

Step-by-step explanation:

Let's let the two numbers be a and b.

The sum of them is 180. Thus:

One of the number is 40% more than the other. In other words, let's let a be the bigger number:

Substitute this into the first equation:

Combine like terms:

Divide everything by 2.4:

So, b is 75.

And their sum is 180. Thus, a is 180-75 or 105.

And we're done!

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
