You have to be able to know the appropriate properties or postulates to apply on the angles or segments to simplify them. An example would be the Angle Addition Postulate. This postulates states that the sum of the individual measures of the interior angles is equal to the measure of the included angle. There are still a lot more properties to choose from depending on the situation.
Answer:
4 milkshakes with whipped cream
Step-by-step explanation:
Let
x ----> the number of milkshakes with whipped cream sold last week
we know that
The total number of milkshakes sold were 10
so
10 milkshakes represent the 100%
by using proportion
Find how many milkshakes represent 40%
therefore
4 milkshakes with whipped cream
Solve for x
so assuming that the fractions are
(9/4)-(1/*2x))=4/x then
get all x on one side
add 1/(2x) to both sides
9/4=(4/x)+(1/(2x))
make common denomators with x and 2x
common denomenator is 2x
4/x times 2/2=8/(2x)
9/4=8/(2x)+1/(2x)
add
9/4=9/(2x)
make common denomators with 4 and 2x
common denomator is 4x
9/4 times x/x=9x/(4x)
9/(2x) times 2/2=18/(4x)
9x/(4x)=18/(4x)
multiply both sides by 4x to clear fraction
9x=18
divide both sides by 9
x=2
Answer:
NO
Step-by-step explanation:
NO, because a triangle must have two acute angles i.e. two angles of less than 90 degrees.
