Should be 26 feet per minute.
because 130/5 equals 26 and so does 52/2

Step-by-step explanation:
3 x pi squared determines the area
Answer:
28 centimeters
Step-by-step explanation:
Solution: Construct a right angle triangle ABC right angled at B.
To construct angle bisector of right angle ,we need to draw arcs from A and C on both the sides with the use of protector.
then join both the intersections of arcs to make the bisector PQ which intersect AC at D.
Now as it is bisecting the right angle B ,therefore as ∠B = 90°
⇒ ∠ABD+∠DBC= 90°
⇒∠ABD+∠ABD= 90°
[ As angle bisector bisects the angle into two equal halves,∴∠A =∠DBC]
⇒2∠ABD= 90°
⇒∠ABD=45° =∠DBC
