Answer:
126 was removed.
Step-by-step explanation:
The total before division took place was
Total = mean * 14
mean = 49
Total = 49 * 14
Total = 685
Now you subtract x from the total
685 - x
And divide by 13 [one number is missing]
(685 - x)/13
and the result = 43
(685 - x ) / 13 = 43 Multiply both sides by 13
685 - x = 43 * 13
685 - x = 559 Subtract 685 from both sides
- x = - 126 Multiply by - 1
x = 126
<span>here are the answer choices
m∠ABC=32°
m∠ABC=64°
m∠ABC=90°
m∠ABC=128°
</span>∠ ABC<span> is less than 90</span>° so the 3rd and 4th option is out.
The most likely answer is 64°. m∠ABC = 64°
32° x 2 = 64°
