A straight line adds up to 180
So the line opposite of 137 should add up to 180
This gives us the equation 137+x=180 then x=43
The triangle also adds up to 180 degrees
So 102+43+x=180
The equation can be simplified to 145+x=180 therefore x=35
So x+?=180 because it is a straight line.
We can substitute x in making the equation 35+?=180
Now we want to solve for the ? so we'll subtract 35 from each side
This leaves us with the equation ?=145
So we now know that the ?=145
The distance of A from the origin.
√(5²+3²+(-2)²)= √(25+9+4)
=√38
=6.2
The distance of B from the origin
√(2²+(-4)²+8²=√(4+16+64)
=√84
= 9.2

Answer:
4 is your value for m.
Step-by-step explanation:
Note the equal sign, what you do to one side, you do to the other. Isolate the variable, m. Do the opposite of PEMDAS.
First, add 5 & m to both sides:
2m (+ m) - 5 (+ 5) = - m (+ m) + 7 (+ 5)
2m + m = 7 + 5
Simplify. Combine like terms:
3m = 12
Isolate the variable, m. Divide 3 from both sides:
(3m)/3 = (12)/3
m = 12/3
m = 4
m = 4 is your answer.
