If the measure of arc AB is 100 degrees, what is the measure of APB?

200

Step-by-step explanation:

I believe is 200 Because If AB was 100 Then all of it would be 200. im sorry if I got the wrong Answer...

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
