What are the values in (y 5) is it (y+5) or (y-5) i cannot answer until given the full problem.
First we need to establish the fact that angles on a straight line ALWYS add up to 180
So, we solve the equation for x which turns out to be 3
But,were not done. The question asks us to find the value of the angle BOC
so we substitute the value of x into the equation for BOC (which is 6x+29)
And then your answer is 47 degrees
This is true because octa- means 8
It would be 0.3 kg, because 3 times a hundred and divided by a thousand is 0.3.
