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
4(xsquared -2) thats the answer
The answer needs to be in mph, or "miles per hour", so let's convert "5 hours and 15 minutes" to pure hours (with no minutes attached)
Since there are 60 minutes in an hour, this means that 15 minutes = 15/60 = 1/4 of an hour (quarter of an hour). I'm going to convert the fraction 1/4 into decimal form 0.25; use a calculator or long division to compute this.
Therefore,
5 hours and 15 minutes = (5 hours) + (15 minutes)
5 hours and 15 minutes = (5 hours) + (0.25 hours)
5 hours and 15 minutes = (5+0.25) hours
5 hours and 15 minutes = 5.25 hours
---------------------------------------------------------
The car travels 183.75 miles (given) for 5.25 hours (value computed above). Use the formula shown below to find the speed or rate
speed = distance/time
s = d/t
s = 183.75/5.25
s = 35
Note: your math book might use "r" instead of "s".
So the speed of the car is 35 miles per hour
