The problems with extra information, are difficult to solve because sometimes, not all data should be used.
Therefore, students begin to doubt the fact that they are not using all the information raised in the problem.
Example:
Problem:
Suppose we have a triangle with a right angle. The problem gives us as data an angle and the sides of the triangle. We want to determine the length of the hypotenuse.
Solution:
Using the Pythagorean theorem we can solve the problem.
The given angle data is an extra information that you should not use for this case.
Answer:
c is 30.
The angles, from left to right, are:
66, 94, and 20.
Step-by-step explanation:
The three angles form a straight angle. In other words, they sum to 180. So, we can write the following equation:
Let's solve for c. Combine like terms:
Add:
Subtract 15 from both sides:
Divide both sides by 5.5:
So, the value of c is 30.
Now, substitute it into each of the angles to find their respective measures.
Left-Most Angle:
We have:
Substitute 30 for c. This yields:
Multiply and add:
Middle Angle:
We have:
Substitute 30 for c:
Multiply and add:
Right-Most Angle:
We have:
Substitute 30 for c:
Multiply and add:
So, our angles, from left to right, are: 66, 94, and 20.
And the value of c is 30.
And we're done!
Answer:
non -uniform
Step-by-step explanation:
because 120km=2 hour
150km=2 hour 30 min
may be the answer is non-uniform.
Answer:
First blank: $5
Second blank: $7.50
Third blank: $11.25
Fourth blank: $13.5
Fifth blank: $15.75
Sixth blank: $18.00
Step-by-step explanation:
Half a number is $2.25, so multiply 2.25 times each half.
First blank:$2.25*2=$5.00
Second blank: $2.25*3=$7.50
Third blank: $2.25*5=$11.25
Fourth blank: $2.25*6=13.50
Fifth blank: $2.25*7=$15.75
Sixth blank: $2.25*8=$18.00
