Using the distance formula, the distance around the park = 190.6 units.
<h3>How to Find Distance Using the distance Formula?</h3>Distance formula is given as, .
To find the distance around the park, find the length of PQ, QR, and PR:
Use the distance formula to find the distance between points P and R:
P(10, 50)
R(80, 10)
PR = √[(80−10)² + (10−50)²]
PR = √[(70)² + (−40)²]
PR = √(4900 + 1600)
PR = √6500
PR ≈ 80.6 units
PQ = |50 - 10| = 40 units
QR = |80 - 10| = 70 units
Thus, the distance around the park = PQ + QR + PR = 40 + 70 + 80.6
Thus, the distance around the park = 190.6 units.

Answer:
Step-by-step explanation:
Total members in the choir = 24 + 36 = 60
a) Percentage of men =
= 4 * 10 = 40%
b) Percentage of women = 60%
c) Number of men =24 + 10 = 34 men
Number of women = 36 + 10 = 46
Total = 34 + 46 = 80
Percentage of men = %
Percentage of women = (100 - 42.5)% = 57.5%

THIS IS THE COMPLETE QUESTION BELOW, ALSO CHECK THE ATTACHMENT FOR THE DIAGRAM
Law of cosines: a2 = b2 + c2 – 2bccos(A) What is the measure of S to the nearest whole degree? 19° 26° 30° 33°
EXPLANATION
Accordingto the law of cosines in
trigonometry, which gives the relationship between the lengths of the sides of a triangle to the cosine of one of its angles.
From the diagram at the attachment, the sides of the triangle are:a=10 ,b=17 ,c=18
The law can is described using the formula below;
a² = b²+ c² – 2*b*c*cos(A)
To get the angle cos(A), we make cos(A) subject of formula
cos(A)=[b²+c²-a²]/[2*b*c]
Then inserting the figures
cos (A)=[17²+18²-10²]/[2*17*18]
cos (A)=0.8382
Then find the inverse of cos(A)
A=arc cos (0.8382)
A=33.05°
A=33°( approximately)
