Calculate the missing measure of the line?

Your answer would be 18.1 cm.

To find this length you have to notice that AC is the hypotenuse of the right-angled triangle ACD. This means that we can find it by using Pythagoras' Theorem (a² + b² = c²), however we need to find the length CD.

We can also find the length CD using Pythagoras' Theorem, because the length CD is the same as the base of the triangle at the top if the shape was split into a rectangle and a triangle.

The height of this triangle would be 11 - 4 = 7 cm, which means we can find CD by doing:

16² - 7² = 256 - 49 = 207 = CD²

Now we can find AC by doing √(CD² + 11²) = √(207 + 121) = √368 = 18.1

I hope this helps! Let me know if you have any questions :)

Answer:

18.1 cm

Step-by-step explanation:

Consider a segment parallel to CD and passing through B.

This segment will form a right-angle triangle with A

It's length would be equal to the length of CD (the missing length)

Height of that triangle:

11 - 4 = 7

CD² = 16² - 7²

CD² = 207

CD = sqrt(207)

AC² = AD² + CD²

AC² = 11² + 207

AC² = 328

AC = 2sqrt(82)

Which is roughly 18.1 cm

The difference of 4 times a number and 7 is 21. Find the number.
USPshnik [31]

Answer:

The number is 7.

Step-by-step explanation:

4n - 7 = 21                  Add 7 on both sides

   4n = 28                       Isolate the variable by dividing 4 on both sides

       n= 7
