Answer:
B
Step-by-step explanation:
Its very simple. Every triangle has a maximum degree of 180°.
We can substract all of the given angles to get our x angle, like so:
x = 180 -102 - 39 = 39°
The answer is 7, 24, 24.
The median is the middle number.
The mode is the number which occurs the most.
The range is the difference between the largest number and the smallest number.
Since 24 is the middle number, it is the median.
Since 24 is also the number which occurs the most often, it is also the mode.
To find range, do 24-7 which is equal to seventeen.
