Answer:
Step-by-step explanation:
All the interior angles are of measure 60 degrees.
We want to find the height of this triangle. Call it h. On the left side of this illustration is a right triangle with height h and base (1/2)(10), or 5.
The ratio of height to base is the tangent of 60 degrees:
h
tan 60 degrees = --------------
5
h
and tan 60 degrees = 1.73 = ------
5
Multiplying both sides of this equation by 5 yields h = 8.66. This is |BD|. This is the same as Answer B.
-6*3 =-18
11*4=44
-18/44. Reduce. Divide top and bottom by 2
-9/22
Answer:
Extra snow needed > 0. 3 inch
Step-by-step explanation:
Given that:
Cancelation occurs when > 2.5 inch of snow accumulates each hour
Accumulation rate = 11/5 inch per hour
Extra snow Accumulation needed to cancel. School ;
Extra snow needed > cancelation volume - current rate
Extra snow needed > (2.5 - 11/5)
Extra snow needed > 0. 3 inch
