Answer:
d = 1.2e
30 dollars
Step-by-step explanation:
To write an expression, define the variables. E will be the number of euros and d will be dollars.
"Euro was equal to about 1.2 American dollars" is one euro equals 1.2 and two euros equals 2.4. So the expression is d = 1.2e.
This means if I have 1 euro, I have 1.2*1 = 1.2 dollars. If I have 2 euros, I have 1.2*2 = 2.4 dollars.
If I have 25 euros then d = 1.2*25 = 30 dollars.
<span>n stands for the number of sides, which is 4.To find the sum of the angles, subtract 2 from the number of sides and multiply by 180.Add all the angles together and set that equal to 360 to solve for x.<span>Plug 32 ° in for x to find the measures of the angles.</span></span>

How am I supposed to be able to answer a question without the info
Answer:
15 m
Step-by-step explanation:
Height of buiding h= 9m
Lenght from building l= 12m
let the length of the rope be x=???
Applying Pythagoras theorem
x^2=h^2+l^2
x^2= 9^2+12^2
x^2= 81+144
x^2=225
square both sides
x=√225
x=15 m
Hence the length of the rope is 15 m
