Answer: Last Option
Step-by-step explanation:
By definition the sum of the internal angles of a triangle must always be equal to 180 °.
This means that:
Now we solve the equation for the variable x
We subtract 12 in both barks of the equation
Divide by 3 on both sides of the equation
Finally the measure of angle ABC is: (56-5)° = 51°
The relative frequency for the class with lower class limit 31 is 8.57%.
<h3>How to calculate the frequency?</h3>
It should be noted that the lowrr class frequency is 31 in this case.
Therefore, the relative frequency for the class with lower class limit 31 will be:
= 3/(6+4+4+9+3+9) × 100
= 3/35 × 100
= 8.57%
Therefore, the relative frequency for the class with lower class limit 31 is 8.57%.
