Answer:
15 feet
Explanation:
Triangle ABC is similar to triangle EDC, meaning they would’ve been congruent if it weren’t for their size.
This also means they don’t have the same side lengths but have the same proportions in comparison to each other.
The sides on the two triangles also correspond with each other. For example, line DC corresponds with line BC.
Knowing that, we can conclude that line ED also corresponds with line AB. Line ED is 12 ft and line AB is 4 ft. To get from 4 to 12, you multiply 3 (4*3=12).
Line EC also corresponds to line AC. So to calculate for line EC, we multiply the length of line AC by 3. 5*3=15, so therefore line EC is equal to 15.

Answer:
$3.45
Step-by-step explanation:
The tip is 15% of his breakfast, that means 15% of 23
That is 15%* 23= 15*23/100= 3.45 $
The tip is $3.45
Have a good day.
Answer:
If we round it to the nearest tenth, our answer would be,
C≈ 17.2 (answer choice C)
Step-by-step explanation:
We will have to use the Pythagorean Theorem to solve this. Since we are not looking for the hypotenuse, but rather the length of one of the legs, we will have to use this,
Let's plug in the values,
Simplify,
Since we know that the opposite of a square is the square root, we are going to apply it.
This tells us that the length of the missing leg would be,
C ≈ 17.2336879396
well, we know is a quadratic, namely of degree 2, so it has two solutions and namely two factors, and whose only zero is 7, well, we can do that by giving that only zero a multiplicity of 2, so we get two of the same zero.
