Answer:
134.4 centimeters
Step-by-step explanation:
This question is asking us for a missing leg on the triangle, lets call it x. Using the Pythagorean theorem (a²+b²=c²), we can figure out what value is missing (either a or b, they are interchangeable).
replace the values in the equation.
83²+x²=158²
get rid of the exponents.
6,889+ x² = 24,964.
subtract 6,889 from 24,964.
x²=18,075.
find the square root on both sides of the equation.
x=134.4432966.
I am assuming you want this rounded to the nearest tenth.
134.4 is your answer.

Answer:

Step-by-step explanation:
We are given with two equations
first equation is 
second equation is

we find the result of subtracting two equation
subtract the second equation from the first, so
first equation - second equation, multiply second equation by -1 and then add it with first equation


Now add both equations, we get

Step-by-step explanation:
DISTANCE FORMULA
D=(SQRT(X2-X1)^2+(Y2-Y1)^2)
SQRT(1-(-1))^2+(3-(-1)^2)
SQRT((2)^2+(4)^2)
SQRT(4+16)
SQRT(20)
2SQRT(5)
the answer is 140 calculate so umm yeah duh I mean 280 lets go baby!!!!
