Answer:

D. 48 in.^2

Step-by-step explanation:

Sides DE and AB are corresponding, and the triangles are similar.

linear scale factor = k = AB/DE = 12/60 = 1/5

area square factor = k^2 = (1/5)^2 = 1/25

area of ABC = area of DEF * area scale factor = 1200 sq in * 1/25

area of ABC = 48 sq in

Answer: D. 48 in.^2

The altitude of an equilateral triangle is 5 cm. what is the length of a side of the triangle?
Grace [21]

Answer:

The length side of the triangle is \frac{10\sqrt{3}}{3}\ cm

Step-by-step explanation:

we know that

The equilateral triangle has three equal sides and three equal internal angles of measure of 60 degrees each.

Let

b------> the length side of the equilateral triangle

Applying Pythagoras theorem

b^{2}=(b/2)^{2}+5^{2}\\\\ b^{2}-(b/2)^{2}=25\\\\ (3/4)b^{2}=25\\ \\b^{2} =25*4/3\\ \\b=\frac{10}{\sqrt{3}}\ cm\\ \\b=\frac{10\sqrt{3}}{3}\ cm

Y-Y1=4(X-X1)
Y-4=4(x-2)
Y-4=4x + (-8)
2. Add 4 on both sides
Y= 4x-4
3. Your answer is
Y=4x-4
