6/3 = 2

pine tree shadow is 15 feet

 15 *2 = 30

 tree is 30 feet tall

Hello! To solve this problem, we can write out and solve a proportion. Set it up like this: 6/3 = x/15. We’re looking for the height of the pine tree, but we know the length of the shadows, so they line up with one another and “x” goes at the top. Let’s cross multiply the values to get 90 = 3x. Now, divide each side by 3 to isolate the “x”. 90/3 is 3. x = 30. The pine tree is 30 feet tall.

Find the length of chord QS <br><br> 1)5<br> 2)33<br> 3)21<br> 4)32
Harrizon [31]

Answer:

Length of Chord QS = 33

Step-by-step explanation:

<u>Length of Chord QS</u>:

QW X WS = PW = WR

12(4x + 1) = 14(3x + 3)

48x + 12 = 42x + 42

48x - 42x = 42 - 12

6x = 30

x = \frac{30}{6} = 5

∴ Length of Chord QS = 12 + 4(5) + 1 = 13 + 20 = 33

The intersecting chords theorem or just The chord theorem is a statement in elementary geometry that describes a relation of the four line segments created by two intersecting chords within a circle. It states that the products of the lengths of the line segments on each chord are equal.  Each chord is cut into two segments at the point of where they intersect. One chord is cut into two line segments A and B. The other into the segments C and D.  This theorem states that A×B is always equal to C×D no matter where the chords are.

Find the length of side x in simplest radical form with rational denominator.
DaniilM [7]

Answer:

sqrt(20)

Step-by-step explanation:

The two perpendicular side lengths are equal, so using Pythagoras theorem:

x = sqrt( sqrt(10)^2 + sqrt(10)^2 )

x = sqrt(10 + 10)

x = sqrt(20)
