Answer:
They sound like objectives for a unit of a math or economics class.
Step-by-step explanation:
Data collection would most likely mean analyzing collected data (looking for trends).
Constructing graphs would probably mean making graphs from a set of data (plotting the information).
Interpreting graphs would mean the opposite of the above definition: would look at a graph and then put that information into written form/
Drawing a line of best fit means making a line on a graph that represents the average of all of the data on the graph.
I hope that this helps!
Answer:
50% of 60 is 30.
100% of 60 is 60, plus 50% is 60+30, which gets you 90.
We know that the summation of angles of a triangle is 180°. Then we can measure angles of B and C by,
m∠A + m∠B + m∠C=180°
65° + (3x−10)° + (2x)°=180°
Solve for variable x by transposing and combing same terms,
5x=180°- 65°+ 10°
x=125/5, x=25
Since we already know the value of x, we can proceed in solving B and C
<span>B=(3x−10)°=3(25)-10=65
C=2x=2(25)=50
</span>Therefore, the answers are x=25, B=65 and C=50.
