Answer:
10.2cm
Step-by-step explanation:
tan(60)=x/3
3tan(60)=x
5.2cm=x
2+3+5.2= 10.2cm
that is the perimeter
Answer:
In 1.25 hours, their combined speed is 40 km, so their speed per hour is 32 km/h
So the answer is B. northbound bicyclist = 18 km/h
southbound bicyclist = 14 km/h
Step-by-step explanation:
the speed of the slower is x and the faster x+4 km/h
that equals 32 km and the speed of the slower is 14 km/hr and the faster 18 km/hr.
in 1h15m the slower goes 17.5 km and the faster 22.5 km
<h3>SOLUTION : </h3>
The radius of the circle is 4 inch and has an arc length of 5.8 inches . We know that if the central angle is 360° then the arc length is 
. Similarly when angle is theta ,
Now substitute respective values , from the given data ,
This is our required answer!
Let cousin = x
Santos. =(3x+4)
Santos. ........49
=>3x+4=49
3x=49
x=15
=> cousin is 15yrs
