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
Answer:(a) n=0.233
Step-by-step explanation:
Given
We Know according to Taylor tool life
V=cutting speed
T=tool life
n=tool life exponent
c=constant
taking log both side
n=0.233
Step-by-step explanation:
i think option a is the correct answer
