You check on manufactured parts in a factory. you need to take measurements to ensure quality. according to the drawing shown, what is the measurement of dimension a? drawing a. ¾ " b. 1" c. 1 ¼ '' d. 1 ½ '' e. 1 ¾ "

A = 1 1/4''

Step-by-step explanation:

The width of the manufactured part is 2 inches (it's shown on the left side). The addition of the radius at the bottom (1/2 inches), the separation of this radius from the edge (1/4 inches) and the measurement of dimension A is equal to the width, then:

1/2'' + 1/4'' + A = 2''

A = 2'' - 1/2'' - 1/4''

A = 1 1/4''

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
