Plz help me I’ve been stuck on this question

If one leg of a right triangle is 9 units and the other leg is 12 units what is the length of the hypotenuse in units

I think its 15

Step-by-step explanation:

a(squared) +b(squared) =c(squared)

so

12×12=144

9×9= 81

144+ 81= 225

and the square root of 225 is 15

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
