umenical answer with no work shown will receive only 1 credit.
13 In the diagram below, AABC has vertices at 11-7,8), B(2.0), and CC-5-8)

(c) Show that AM is perpendicular to BC ponts]

answer: 42

use a calculator to find that 845/73 = 11.575

the whole part of the answer is 11. multiply this by 73 to get 11*73 = 803.

subtract that result from 845 to get 845 - 803 = 42

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

answer: i believe it is c

step-by-step explanation:

because 5+4=9 so it would be 3^9
