Answer:
13.856 feet
Step-by-step explanation:
The height of the tree and its shadow forms a right angle. Together with the line joining the pit of the shadow and the tree make a right triangle.
We can use the trigonometric ratio tangent to find its height.
tan = opposite/adjacent
tam 30° = x/24
height = 24 × tan 30°
= 24 ×0.57735
= 13.856 feet
Find multiples of 30 and 40:
30: 30, 60, 90, 120, 150
40: 40, 80, 120, 160
The least common multiple is 120, so every 120 minutes they willl both ring.
1 hour = 60 minutes:
120/60 = 2 hours.
The bells ring together every 2 hours.
8 + 2 = 10 am
10 + = 12pm
12 + 2 = 2 pm
The bells will ring together at am, 12 pm and 2 pm.
Answer:
x = 110° (vertically opposite angel)
The second pair because the ratios between the sides are equal
Answer:53.38 is the answer
Step-by-step explanation:
The radius is always half of the diameter so half of 17 is 8.5. 8.5x3.14 is 26.69. Then you add 26.69+26.69 to get the answer. (I’m not positive that this is correct)
