. Kite QRST has a short diagonal of QS and a long diagonal of RT. The diagonals intersect at point P. Side QR = 17m, diagonal QS
trapecia [35]

Answer:

495 meter²

Step-by-step explanation:

In the given kite QRST,

PQ = PS = 15 meter

QR = 17 meter

We have to find the area of the kite.

Since kite is in the form of a rhombus.

and rhombus is = \frac{1}{2}  (Diagonal QS) × (Diagonal RT)

In Δ QRP,

17² = 15² + RP²

\sqrt{17^{2}-15^{2}} = RP

RP=\sqrt{289-225}

= √64 = 8 meters.

So RT = RP + PT = 8 + 25 = 33 meter.

Now area of kite = \frac{1}{2} (30) (33) = 495 meter²

5 divided by 2,165 equals?
Mekhanik [1.2K]

answer:

1/433 (decimal: 0.002309)

step-by-step explanation:

5/2,165

= 1/433

to change 1/433 to decimal we'll divide the numerator by the denominator-

1÷433

=0.00230946882

so we're going to round to the ten-millionths place

5 or more raise the floor, 5 or less let it rest

4>5

so 0.002309

good luck :)

i hope this helps

brainliest would be highly appreciated

have a nice day!

K/5+14=13<br> what is the answer and how you got the answer.
abruzzese [7]

Answer:

\frac{k}{5+14} = 13 : k = 247\\

Step-by-step explanation:

\frac{k}{5+14} = 13

Multiply both sides by 19:

\frac{19k}{5+14} = 13 * 19

Simplify:

k = 247

Hope I helped, if so may I get brainliest and a thanks?

Thank you, have a good day! =)
