Step-by-step explanation:
you could multiply 3 by everything to get rid of the fraction but you would still have to the equation after multiplying
The sum of all interior angles in a polygon is
180(n - 2), where n = the number of sides in the polygon.
now, notice this figure above, it has 5 sides, namely is a PENTAgon, so the sum of all its interior angles is 180( 5 - 2), or 540, therefore
The answer is 7
because the equation is |(3)(-2)-1|
Answer:
83°
Step-by-step explanation:
We khow that the sum of a triangle's angle is 180°
- x is unkhown
- an angle with 43° and another unkhown one
We should calculate the first one wich is given by : 180-126= 54
now finally :
=83°
Convert to:
42 4 168
---- x ---- = ------
