No such thing as cot (61,4). I think you meant to say cot (61.4°). See the difference?
So, cot (61.4°) is approximately -0.139844.
Rounded to 3 decimal places we get -0.140.
If m∠ABC = 45° and m∠ECD = 45°, which statement explains whether the AA similarity postulate can be used to determine whether ΔBAC ~ ΔEDC?
answers:
Yes, the AA similarity postulate can be used because a reflection over line f will establish that segment AB ≅ segment DE.
Yes, the AA similarity postulate can be used because a reflection over line f will establish that ∠ABC ≅ ∠DEC.
No, the AA similarity postulate cannot be used because a reflection over line f will establish that segment AB and segment DE are not congruent.
No, the AA similarity postulate cannot be used because a reflection over line f will establish that ∠ABC and ∠DEC are not congruent.
Answer:
B would be the answer
Step-by-step explanation:
If you reflect the triangle ABC onto EDC then you will see that they are congruent and equal.
this means that <ABC ~ <EDC
The AA postulate states that if two corresponding angles of two or more triangles are congruent then the triangles are similar. If you translate ABC onto EDC you can see that all of the angles let alone two are all congruent thus proving that ABC = EDC
Pls mark brainliest if I helped.. Thanks:)
Option (B) is the correct answer.
What is AA postulate?According to the AA postulate, triangles are comparable if two matching angles of two or more triangles are congruent.
Given that,
∠ABC = 45° and ∠ECD = 45°
Angle-Angle or AA similarity postulate,
When triangle ABC reflect onto EDC, then triangle will be congruent and equal.
Implies that ΔABC ≅ ΔDEC.
Hence, option (B) is the correct answer.

PLEASE HELP. "ANSWER ONLY IF YOU KNOW THE ANSWER"
Answer:
The x intercepts are (-5, 0) and (2, 0)
The y intercept is (0, -10).
Step-by-step explanation:
The x intercepts are (-5, 0) and (2, 0)
When you set the numbers x + 5 and x - 2 equal to zero, you solve for x and that becomes the x-intercept.
The y intercept is (0, -10).
When you multiply the numbers, you result in [tex]x^{2} +3x - 10[/tex].
Then, set the x values to 0 and evaluate. That leaves you with -10, which is the y-intercept.

A car has a 16-gallon fuel tank. When driven on a highway, it has a gas mileage of 30 miles per gallon. The gas mileage (also called "fuel efficiency") tells us the number of miles the car can travel for a particular amount of fuel (one gallon of gasoline, in this case). After filling the gas
tank, the driver got on a highway and drove for a while.How many miles has the car traveled if it has 10 gallons of gas left in the tank?
and write an equation that represents the relationship between the distance the car has traveled in mikes, d, and the amount of gas left in the tank in gallons, x
Answer:d=(16-x)30
Step-by-step explanation:
The car traveled 600 miles if it has 10 gallons of gas left in the tank.
What is the equation?The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that is equal.
To determine the equation that represents the relationship between the distance traveled by car and the amount of gas left in the tank.
Let the distance traveled by car would be d miles,
and the amount of gas left in the tank would be x gallons
Since the car had a 16-gallon fuel tank
So the amount of gas left in the tank would be 16 - x
When driven on a highway, it has a gas mileage of 30 miles per gallon.
To find the equation of the distance we have to calculate the product of gas left in the car and the mileage of the car.
So the required equation as:
⇒ d = (16-x)30.
If it has 10 gallons of gas left in the tank
Substitute x = 10 in the above equation, we get
⇒ d = (16-10)30.
⇒ d = (20)30.
⇒ d = 600.
Therefore, the car traveled 600 miles if it has 10 gallons of gas left in the tank.
