Mai is visiting Paris to see the Eiffel Tower. She is 80 feet away
Jlenok [28]

Answer: height of the tower is 1064 feet

Step-by-step explanation:

We want to determine the height of the tower.

Assuming her line of sight of the top of the tower is a straight line, then a right angle triangle is formed. The height, h of the tower represents the opposite side of the triangle. Her distance from the foot of the tower represents the adjacent side of the triangle.

To determine h, we would apply the tangent trigonometric ratio which is expressed as

Tan θ = opposite side/adjacent side

Therefore,

Tan 85.7 = h/80

h = 80tan 85.7

h = 1064 feet

The school day begins at 7:55 a.m. and ends at 2:40 p.m. how long are you in school?
Mademuasel [1]

Think:

7:55 a.m. is 5 minutes (5/60 hrs) before 8 a.m.;

from 8 to noon it's 4 hours, and from noon to 2:40 p.m. is 2 2/3 hours.

Thus, you're in school 5/60 hrs + 4 hrs + 2 2/3 hrs, or

6 2/3 hrs + 5/60 hrs, or 6 40/60 hrs + 5/60 hrs, or

6 45/60 hrs, or 6 3/4 hrs.

Of course there are other ways in which you could do this problem:

4 hrs 5 min plus 2 hrs 40 min comes out to 6 hrs 45 min, or 6 3/4 hrs.

Base of a prism is a right triangle with legs 3 feet and 4 feet. The height is 13 feet , what is the volume?
julsineya [31]

Answer:

Triangular prisms

Remember the formula for calculating volume is: Volume = Area by height. V = A X h.

For a triangle the area is calculated using the formula: Area = half of base by altitude. A = 0.5 X b X a.

So to calculate the volume of a triangular prism, the formula is: V = 0.5 X b X a X h
