The port support for a window
air conditioning unit forms a triangle and an exterior angle. The sides are (
5x - 6) degreesand the other angle is 3x degrees and last angle is 90 degrees.
The su, of the interior
angles of the triangle is 180
( 5x - 6) + 3x + 90 = 180
X= 12, so the angles are 54
and 36
The exterior angle will also
form a 180 degree with the interior
Depending which exterior
angle
1. ) 180 – 54 = 126
2.) 180 – 36 = 144
You simply divide 678 by 3 and get 226.
Answer:
It is an Integer, but it can also be a rational number.
Step-by-step explanation:
My math teacher told meh
What we know:
Petrolyn motor oil is a combination of natural oil and synthetic oil. It contains 7 liters of natural oil for every 5 liters of synthetic oil.
What we need to find:
If 355 liters of synthetic oil are used, how many liters of petrolyn oil will be made?
Set up a proportion to find how much natural oil is used.
7L natural oil/5L synthetic oil = x/355 synthetic oil where x=natural oil
7/5=x/355
(5)(x)=(7)(355) cross multiplied
5x=2485 simplified
5/5x=2485/5 multiplicative inverse
x=497L
Now, add both synthetic oil and natural oil to find amount of petrolyn oil.
355 L synthetic oil + 497 L natural oil= 852 L of petrolyn oil
