Answer:
I think it is the second one because -4 is the least
Step-by-step explanation:
180 is the degree of the whole angle so you subtract 180 from 77 to get P
180-77=103
P=103
Answer:
x = 18 or x = -12.
Step-by-step explanation:
||x-3|-5| = 10 only if |x-3|-5 = 10 or |x-3|-5 = -10, i.e., if |x-3|=15 or |x-3|=-5; but |x-3| cannot be equal to -5, because |x-3| should be a non-negative value. Therefore, the first equation is true only if |x-3|=15. |x-3| = 15 only if x-3 = 15 or x-3 = -15, i.e., x = 18 or x = -12. We can verify this in the following way: ||18-3|-5|=||15|-5|=|10|=10 and ||-12-3|-5|=||-15|-5|=|15-5|=|10|=10. This verify that our solution is correct.
If I’m not mistaken 174 is your median
We use the equation x=810/5.4, which is converted to 8100/54. The answer is that the model was made on a 1in=150ft scale
