A triangle has sides with lengths of 18 inches, 24 inches, and 30 inches. Is it a right triangle?

It is a right triangle

Step-by-step explanation:

Right Triangle

A right triangle has one of its internal angles of 90°. If such triangles, Pythagora's theorem must stand.

Being a and b the shortest sides of the triangle and c the longest side (hypotenuse), then:

The shortest sides of the given triangle are 18 and 24, and the longest side is 30, thus the following condition must be met to prove it's a right triangle:

Since the condition is met, we can conclude it is a right triangle

i think the answer is seven, for if i'm being useless °ω°

step-by-step explanation:

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
