APQR is inscribed in a circle with P=60, Q = 80, and R = 40. What are the measures of PQ, QR, and PR?

Sergeeva-Olga [200]

Answer:

PQ:80

QR:160

PR:120

Step-by-step explanation:

$PQ=2x$ ∠ $R$

$=2$ × $40$

= $80$

$QR=2$ × $m$ ∠ $p$

$=20$ × $80$

$=160$

$PR=2$ × $m$ ∠ $Q$

= $2$ × $60\\$

= $120$

hope it helps

have a great day!!

Find the distance between the points:

lesantik [10]

To calculate distance between two points we use the distance formula sqrt((x2−x1)^2+(y2−y1)^2).

To start, we find the square of the distance between x1 and x2 and y1 and y2. The distance between x1 and x2, or 1 and 3, is 2. The distance between y1 and y2, or 3 and -4, is 7.

Now we square 2 and 7 and add them together to get 4 + 49 = 53.

The last thing we do to find the distance is take the square root of 53. 53 is not a perfect square and is also a prime number so our answer in simplest form is still sqrt53.

Find x and y, given that line WS and line VT are parallel. Show all work!

bulgar [2K]

In the given diagram, the traingles USW and UTV are similar triangles and thus the following ratio equality applies to them.

$\frac{VT}{WS} =\frac{VU}{WU}=\frac{TU}{SU}$ ..........(Equation 1)
