answer:
5 is the answer
Step-by-step explanation:
I don't know how I got my answer but please try
<ABC would equal 106
seeing in triangle ABD angle A equals 67 you would multiply that by 2 and then subtract it from 180 to get 46, and then triangle DBC all the angles would equal 60. so then add 46 to 60 to get 106 the measure of <ABC
Mean = (12 + 13 + 14 + 9 + 7 + 8 + 15 + 10) / 8 = 88/8 = 11
Median = 7, 8, 9, 10, 12, 13, 14, 15 = 11 (between 10 and 12)
Mode = None because there are no numbers that occur more than once
Set up a proportion to answer this question.
3.5/ 5 = x/ 7
Cross multiply
5x = 24.5
Now divide by 5 on both sides.
x = 4.9
Your answer should be: The enlarged photograph is 4.9 in wide.
