Which of the following explains the relationship between angles a and b? A. Adjacent angles
B. Corresponding angles
C. Complementary angles
D. Vertical angles

A. Adjacent Angles

If you look at the image given, there is a line which have the points, K and J. Angles A and B share that line and share the same vertex point which is J. Just by looking at it, you should be able to understand that they add up to 180 degrees since they are both right angles or 90 degree angles (90+90=180). When two angles have all these, they are Adjacent angles.

step-by-step explanation:

107 units

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
