Alex draws the scale model shown as a plan for a large wall mosaic. 10 cm 12 cm a. The wall is 10 m wide and 7 m high. What are the dimensions of the largest mosaic he can make on that wall? Explain. b. He will use 2-cm square tiles to make his mosaic. How many tiles will he need? Explain how you found your answer.

answer: 2/4

step-by-step explanation:

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
