Classify the quadrilateral. Then find the value(s) of the variable(s).

Step-by-step explanation:

The shape we see is a kite.

The measures of the triangles must add to 180°.

27 + 90 + x = 180°

117 + x = 180°

x = 63°

3 = 63°

We can also solve for 1 and 2. 2 is a right angle so 90° and 1 is a reflection of the 27° angle on the other side, so it also is 27°.

1 = 27°  2 = 90°  3 = 63°

I'm always happy to help :)

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
