Answer:
66
Step-by-step explanation:
mean = the sum of the value / the number of the value
when we calculate the some must be 385 so the sum of the given value gives 319 so to reach the average 77 she must score 66
The tangent of the angle gives the ratio of the height of the lighthouse to the boat's distance
.. tan(angle of depression) = (lighthouse height)/(boat distance)
Then the distance to the boat is
.. boat distance = (lighthouse height)/tan(angle of depression)
We want to find the difference between two distances, so
.. boat travel = (lighthouse height)*(1/tan(first angle) -1/(tan(second angle))
.. = (200 ft)*(1/tan(17°31') -1/tan(46°41'))
.. ≈ 445.10 ft
The equation for slope between two points is (y1-y2)/x1-x2
Plug the points into the equation
-5-(-10)/-2-3
5/5
m=1
To find the equation, use y-y1=m(x-x1)
y-(-5)=1(x-(-2))
y+5=x+2
y=x+2-5
y=x-3
The answer is b. Thank you
Answer
From the construction that James is doing the
next step that he should take would be: Use the
circumcenter to determine the center of the
circle.
How to construct a circle from a triangle
In order to construct a circle for the triangle, one
would have to find the perpendicular bisector of
all sides of the triangle.
From the established circumcenter, a pair of
compass would be used to contruct the circle.
