it is 100% because 148-74=74
74/74=100%
Answer:
The top of the escalator is 10 ft from the ground floor
Step-by-step explanation:
we know that
The function sine of angle of 39.81 degrees is equal to divide the opposite side to the angle of 39.81 degrees (distance of the top of the escalator from the ground floor) by the hypotenuse (15.5 ft)
so
Let
h ------> distance of the top of the escalator from the ground floor
sin(39.81°)=h/15.5
h=(15.5)sin(39.81°)=9.9 ft
Round to the nearest foot
h=10 ft
Answer:
9 miles
Step-by-step explanation:
use Pythagoras theorem
15 squared - 12 squared = 81
square root of 81 is 9
