To find the length of the base, you must first find the length of the sides, or the value of x. Because it is an isosceles triangle, the legs are equal to each other.
2x + 4=x + 8
x=4
Now that you have found x, plug it into the equation for the base.
5(4) - 2
20 - 2
18
Final Answer: 18
Hope this helps!! :)
We know that
speed=distance/time
1) <span>Sarah rides her horse for 2 1/6 hrs with a constant speed of 6 km/hr
time=2 1/6 hrs----> 13/6 hrs
speed=6 km/h
distance=speed*time----> 6*(13/6)---> 13 km
2)</span><span>for another 2 hours and 5 minutes with a constant speed of 12 km/hr
time=2hrs+5 minutes----> 2+(5/60)--> 125/60 hrs
speed=12 km/hrs
distance=speed*time----> 12*(125/60)---> 25 km
3) find the </span><span>average speed for the total trip
total distance=13 km+25 km----> 38 km
total time=(13/6)+(125/60)----> (10*13+125)/60----> 4.25 hours
speed=38/4.25----> 8.94 km/hrs
the answer is
8.94 km/hrs</span>
