Answer:
IM NOT SURE WHAT you mean
Step-by-step explanation:
1. -2 + 15 = 13
If the temperature is -2 and it rises 15 degrees, the new temperature is 13 degrees.
2. The temperature rose 15 degrees
-6 + 9 = 15
Answer:
The perimeter of the Rectangle JKLM is 32 unit.
Step-by-step explanation:
Consider the provided coordinates.
Rectangle JKLM: J(-3, 8), K(-3,-1), L(4, -1), M(4,8)
First plot the points as shown in figure:
The required figure is shown below:
Now find the distance between JK by using the distance formula.


Therefore, the length of JK is 9 unit.
Now find the length of the side JM

Therefore, the length of JM is 7 unit.
The perimeter of rectangle is: 
Therefore,



Hence, the perimeter of the Rectangle JKLM is 32 unit.
Answer:
The guy wire lenght is 500 ft.
Step-by-step explanation:
The Pythagorean Theorem says the sum of the squares two adyacent sides is equal to the square of the opposite side.
Applied in this example, we can rephrase it as:
The sum of the square of the pylon height with the square of the distance from the guy wire tip to the pylon is Equal to the square of the Guy wire lenght.
So:

Remaining angle = 180-90-60=30
by sine rule
8/sin30 = x/sin90
x = 8/0.5=16
