Answer:
Step-by-step explanation:
a
sum of angles of a quadrilateral=360°
4x+5x+20+5x-10+3x+10=360
17x=360-20
17x=340
x=340/17
x=20
b.
sum of angles= (n-2)×180
where n is the number of sides.
5x+4x+2+5x+6+2x-2+3x+5+x-10=(6-2)×180
20x+1=720
20x=719
x=35.95
Answer:
<u>Bill must give Jack a handicap of 165 yards to finish the race at the same time. The correct answer is A. 165 yards.</u>
Step-by-step explanation:
1. Let's review the information given to answer the question correctly:
Bill can run 440 yards in 55 seconds
Bill speed = 8 yards per second (440/55)
Jack can run 440 yards in 88 seconds
Jack speed = 5 yards per second (440/88)
2. How great a handicap must Bill give Jack for the boys to finish the race at the same time?
The total duration of the race will be 55 seconds
Using Rule of Three Simple, we have that:
Jack will run 55 * 5
Jack will run 275 yards in 55 seconds
Bill must give Jack a handicap of 440 - 275 yards
Bill must give Jack a handicap of 165 yards to finish the race at the same time. The correct answer is A. 165 yards.
AC = 75 x 2 = 150 degrees
The answer is 2/25, this should be hepful!
