Answer:
Based on the assumption that the angle of the triangle at the cave entrance is a right angle, the angle Devora turned before walking to the treasure chest is approximately 57 degrees.
Step-by-step explanation:
A sketch of the triangle formed is attached where E is the entrance of the cave, C is the treasure chest and T is the treasure itself.
Using the cosine trigonometric ratio, we have that
Finding the arccosine of 0.5393 gives 
The average is 80*
80* + 80*=160 divided by 2 is 80*

Step-by-step explanation:
I dont know how to do it on a number line but am positive them are the right answers.
Answer
try the inequality x >3
Step-by-step explanation:
because the circle is open and the line would have started at the 5 so the line would be going > and the circle ends at the 3
Srry if im bein confusing lol
<span>x + 9 = 2(x - 1)^2
x + 9 = 2(x^2 - 2x + 1)
x + 9 = 2x^2 - 4x + 2
</span>2x^2 - 4x + 2 - x - 9 = 0
2x^2 - 5x -7 =0
