How do you know 37? I don't understand, do you add another line connecting it to make a whole triangle or ..I don't understand..

Answers

Answer 1

Answer: Hello,
The 3th angle of the triangle is the supplement of 3x-8:
180-(3x-8)=180-3x+8=188-3x

The sum of all angles of the triangle is 180
180=2x+21+188-3x
==>180=-x+21+188
==>x=21+188-180
==>x=21+8
==>x=29

An elevator is going 180 feet above the first floor each second the 12 feet it descent 12 feet

Answers

a) The change in the height of the elevator each second is negative 12.

b) The complete table for Time and Change in attached at the end.

c) The elevator will take 15 seconds to get to reach the first floor.

d) The height of the basement floor with respect to the first floor 48 feet.

a. The change in the height of the elevator each second is a decrease of 12 feet.

Since it's descending, the change is negative, so the integer is -12.

b. Completing the table attached at the end.

c. Now, the Estimated time

$\text{Estimated time} = \frac{\text{Total height}}{\text{Change in height per second}}$

$\text{Estimated time} = (180)/(-12)$

$\text{Estimated time} = -15 \ \text{seconds}$

However, since time cannot be negative, the negative sign in this case just indicates the direction (descending).

So, the elevator takes 15 seconds to get to the first floor.

d. From the first floor, it takes 4 seconds to reach the basement floor. The elevator descends 12 feet each second.

So, the change in height during these 4 seconds is:

$\text{Change in height} = 4 \ \text{seconds}\cdot (-12 \ \text{feet/second}) = -48 \ \text{feet}$

The height of the basement floor with respect to the first floor is a decrease of 48 feet.

So, the basement floor is 48 feet below the first floor.
