Answer:
number 1,2,4
Step-by-step explanation:
these are all equal sides
Add up the numbers of the sides you have then subtract it from the Magic total
Answer:
(-6,-5)
Step-by-step explanation:
Let a function be f(x)
So, f(x-a) would be the same function BUT translated a units to the RIGHT.
So, that changes all x coordinates a units to the right (+a) and all the y-ccordinates remains same.
Our function goes through the transformation f(x-2), which means 2 units to the right, so we "ADD" 2 to all x-coordinates and y remains same.
Thus, the point (-8,-5) would become (-8+2,-5) = (-6,-5)
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
Answer:
SW =XW and ST=XU and UW=TW
Step-by-step explanation:
All are true and correct since the two triangles are congruent
