Answer:
H = 120°
Step-by-step explanation:
The sum of the internal angles of a polygon with n sides is given by the formula:
S = (n-2)*180
So, for a pentagon, we have n = 5, then:
S = (5-2)*180 = 540°
So we have that:
M + A + T + H + S = 540° (eq1)
M = T = H (eq2)
A + S = 180° (eq3)
Using the second and third equation in the first one, we have:
H + H + H + 180 = 540
3H = 360
H = 120°
Answer: 
Step-by-step explanation:
First find slope m. From observing the equation we can see that there are two points on the line. They are (-5,-4) and (-1,-6). Using the formula to find slope rise/run we get m = -0.5.
Now we use the point-slope formula to start the switch to the slope-intercept formula. Using (-1,-6) as our x and y values and switching m=-0.5 we get y + 6 = -0.5 ( x + 1). Simplify and we get y + 6 = -x/2 - -0.5. Subtract 6 from both sides and the final equation is y = -x/2 - 6.5.

Step-by-step explanation:
From the question the emerald was located at a depth which is between -1/2 and -1 2/3 meters
This statement can be written as

To get the depth, you find the depth of the emerald location, you find difference between the two mentioned depths

Change first term to improper fraction

Find the LCM to solve the operation the involves the fractions.The Least common multiple here is 6 i.e 3*2


The number that could represent the depth at which the emerald was located is
