Which expression will help you find the area of the triangular bases?

The two sides of the triangle are equal so by the property that : If  opposite sides of a triangle are equal then the opposite angles are also equal .

Area of triangle = 1/2 multiplied by base and also multiplied by height

A =1/2*b*h

So, we can conclude that the opposite angles are 90 + 90 degrees = 180 degrees (as the angles are equal)

Therefore, c)1/2 *8*3  is right

30 miles

step-by-step explanation:

we know that 60 seconds equals 1 minute and 60 minutes 1 hour

44 ft       60 sec     60 min     158400   ft

  *   *   =

1 sec       1 min       1 hour         hour

we know that there are 5280 ft per mile

158400   ft       1 mile         30 miles

  *   =

1   hour               5280 ft     1 hour

so in 1 hour   it can travel 30 miles
