C
Step-by-step explanation:
let hypotenuse of triangle with 60°=y

Answer:
ΔA'B'C' is a reduction of ΔABC and ΔA'B'C' is similar to ΔABC.
Step-by-step explanation:
It is given that the triangle ABC is dilated to produce triangle A'B'C' with scale factor 3/4.
If a figure is dilated then preimage and image are similar.
If scale factor is between 0 to 1, then preimage is reduction of image.
If scale factor is more that 1, then preimage is enlargement of image.
If scale factor is 1, then preimage is congruent to the image.
We know that

So,

Therefore, the ΔA'B'C' is a reduction of ΔABC and ΔA'B'C' is similar to ΔABC.

Answer:
20 m²
Step-by-step explanation:
<u>Formula (Area of triangle):</u>
<u />
From the triangle, we can see that the base of the triangle is "7 + 3" m and the height of the triangle is "4" m.
<u />
Simplify the right-hand-side as needed to evaluate the area.
<u />
<u />
Therefore, the area of the provided triangle is 20 m².
