To do this problem, you need to use the Pythagorean thermion I think.
Here is what I got as an answer
22.5 km
<em>In decimal form, a = 114.5; b = 25.5</em>
We will write this as a system of equations, where 
and 
are the two angles.
We will use substitution to solve this system. We know what equals, so we plug that into the second equation.
Combine the like terms.
Add 
on both sides.
Divide both sides by 
.
Now just subtract that from 
.
Answer:
18 - (-12)
Step-by-step explanation:
Final temp. - Initial temp. = the change in temperature
By -12, we're indicating that is below zero (which is obvious) meaning that it is not in the "normal" scale nor in the imaginary scale of numbers. So, we can operate the following...
18 - (-12) = 30
So the temperature changed by 30 values or the temperature increased by 30 values, because the number is positive.
One solution let's find that
Answer:
The sum of the lengths of any two sides of a triangle must be greater than the length of the third side. ... No; The sum of the lengths of any two sides of a triangle must be greater than the length of the third side. ANSWER: No; 9.
