The correct statement to find the measure of EC is: Create a proportion with the legs of the triangles where segment BC is the same measure as segment AB. Add the length of segments BC and BE to find the length of segment EC.
Since BE is parallel to AD, triangles ADC and BEC are similar by the Alternate Interior Angles Theorem. Therefore, the ratio of corresponding sides of these triangles is equal:
AD / BC = DC / EC
Since AD = 4√138 m and BC = AB = 6√3 m, we have:
4√138 / 6√3 = DC / EC
Simplifying:
2√3 / 3 = DC / EC
Now, we know DC = BE = √138 m. Let's substitute that value:
2√3 / 3 = √138 / EC
Now, solve for EC:
EC = (√138 * 3) / (2√3)
EC = 3/2 * √(138/3)
EC = 3/2 * √46
Thus, the measure of EC is 3/2 * √46 m. The correct statement provided earlier explains the process to find this value.

Answers
Answer:
Points ( 0, 13) , ( 30, 18) , ( 90 ,28)

Answer:
64 ounce bottle of orange juice has a greater percent of water
Step-by-step explanation:
Case 1) An 80 ounce bottle of apple juice contains 32 ounces of water
Total quantity of bottle = 80 ounces
Amount of water = 32 ounces
So, Percent of water = [tex]\frac{32}{80}[/tex] x 100
= 40%
Case 2) An 64 ounce bottle of orange juice has 48 ounces of water
Total quantity of bottle = 64 ounces
Amount of water = 48 ounces
So, Percent of water = [tex]\frac{48}{64}[/tex] x 100
= 75%
Hence 64 ounce bottle of orange juice has a greater percent of water

What is the value of the x variable in the solution to the following system of equations?
2x - 3y = 3
5x - 4y = 4
Answers
Answer:
x = 0
Step-by-step explanation:
Solve 2x - 3y = 3 for x:
[tex]2x - 3y = 3[/tex] [tex]2x - 3y + 3y = 3+ 3y[/tex] (add 3y to both sides)[tex]2x = 3y + 3[/tex] [tex]\frac{2x}{2} = \frac{3y+3}{2}[/tex] (divide both sides by 2)[tex]x = \frac{3}{2}y + \frac{3}{2}[/tex]Substitute 3/2(y) + 3/2 for x in 5x - 4y = 4
[tex]5x - 4y = 4[/tex] [tex]5(\frac{3}{2}y + \frac{3}{2}) - 4y = 4[/tex] [tex]\frac{7}{2}y + \frac{15}{2} = 4[/tex] (simplified both sides of equation)[tex]\frac{7}{2}y + \frac{15}{2} - \frac{15}{2} = 4 - \frac{15}{2}[/tex] (subtract 15/2 from both sides)[tex]\frac{7}{2}y = -\frac{7}{2}[/tex] [tex]\frac{7}{2}y * \frac{2}{7} = \frac{-7}{2} * \frac{2}{7}[/tex] (multiply both sides by 2/7)[tex]y = -1[/tex]Substitute -1 for y in x = 3/2(y) + 3/2
[tex]x = \frac{3}{2}y + \frac{3}{2}[/tex] [tex]x = \frac{3}{2}(-1) + \frac{3}{2}[/tex] [tex]x = -\frac{3}{2}+ \frac{3}{2}[/tex] (simplified both sides of equation)[tex]x = 0[/tex]Therefore, the value of the x-variable is 0.

A semicircle with diameter 8 inches is connected to a triangle with a base length of 8 inches. The height of the triangle is 3 inches.
What is the area of the composite figure?
Answers
Answer:
Step-by-step explanation:
Area of the semicircle = pi * r^2 / 2
d = 8
r = d/ 2
r = 8/2 = 4 inches
Area = pi * 4^2 / 2
Area = 3.14 * 8
Area = 25.12 square inches
Area of the triangle
Area = 1/2 * b * h
b = 8
h = 3
Area = 1/2 * 8 * 3
Area = 12 square inches
Total area = 25.12 + 12
Total area = 37.12 square inches
