Answer:
see the explanation
Step-by-step explanation:
First way
we know that
The sum of the interior angles of a triangle must be equal to 180 degrees
so
In this problem
37+97+134 > 180
therefore
At least one of Franklin's measures is incorrect
Second way
we know that
A triangle can only have at most one obtuse internal angle.
In this problem the triangle has two obtuse internal angles
Remember that an obtuse angle is an angle greater than 90 degrees
therefore
At least one of Franklin's measures is incorrect
Divide the second price by the second pounds. 9.95 / 5 = 1.99
So for every pound you get you pay 1.99 dollars. The second deal is better.
Tan^-1 = 72.81° is your answer, use basic SOHCAHTOA functions
Answer:
23 + 2x
Step-by-step explanation:
17 + 6 + 2x
23 + 2x
The slope of the graph will correspond to the unit rate.
The unit rate is the amount it cost for one minute.
From the graph at x = 1, the rate is $4.75.
