Answer:
Step-by-step explanation:
Supplementary angles are angles equal to 180°.
Therefore:
Now that we have our equation, let's distribute the 
and the 
into the parentheses they are next to:
Combine like terms:
Subtract 
from both sides of the equation:
Divide by the coefficient of 
, which is 
:
~
Check your work by substituting 
into one of the equations above:
It's correct!
Answer:
0.7173 miles per hour
Step-by-step explanation:
divide 1.265 by 2.3
Shadow length is proportional to object height.
(tower height)/(tower shadow length) = (tree height)/(tree shadow length)
(tower height)/(72 ft) = (27 ft)/(6 ft)
(tower height) = (72 ft)*(27/6)
(tower height) = 324 ft
The cellular telephone tower is 324 ft tall.
Answer:
The resultant force magnitude is 129.90 pounds at angle of 60°
Step-by-step explanation:
Two given forces and resultant force form right triangle. The first force (150 pounds) is hypotenuse, the second force ( 75 pounds) and resultant force are right sides of the right triangle.
Then we can write pythagorin theorem
R= √150∧2 - 75∧2 = √ 22500-5625 = √16875 = 129.90
Good luck!!!
