In AABC, the measure of ZB=90°, AC = 50, CB = 30, and BA = 40. What ratio
represents the tangent of ZA?
Help ASAP please

tanA = 3/4

General Formulas and Concepts:

Trigonometry

Step-by-step explanation:

Step 1: Define

Looking at ∠A, finding tangent

Step 2: Identify

opposite leg of ∠A = CB = 30

adjacent leg of ∠A = AB = 40

Step 3: Write ratio

And we have our final answer!

is there any photos or whatever?

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
