Step-by-step explanation:
x + 107 + 34 = 180
x + 141 = 180
x. = 180 - 141
x = 39
the above method can be used if the angles are the interior angles of triangle or for all angles in a straight line .
A shape with 4 equal sides.
Answer:
cubes are 3-d while squares are 2-d so in order to solve them you need different equations.
The correct answer for this question is that the unit rate is 5:1. We
can work this out by simplifying down the 2 commercials to every 10
songs ration, so that 10:2 becomes 5:1. We can work this out by halving
the original ratio to simplify it.
45m+10n-30m
15m+10n
I believe this is right.
