The answer is (c). The picture shows that all of the angles and sides are equal, meaning that it's both equilateral and equiangular.
Tan 135 = -1
so rectangular coordinates are (-7 sqrt2, 7 sqrt2)
Answer:
86.6
Step-by-step explanation:

Here, AB represents height of the building, BC represents distance of the building from the point of observation.
In the right triangle ABC, the side which is opposite to the angle 60 degree is known as opposite side (AB), the side which is opposite to 90 degree is called hypotenuse side (AC) and the remaining side is called adjacent side (BC).
Now we need to find the length of the side AB.
tanθ = Opposite side/Adjacent side
tan 60° = AB/BC
√3 = AB/50
√3 x 50 = AB
AB = 50√3
Approximate value of √3 is 1.732
AB = 50 (1.732)
AB = 86.6 m
So, the height of the building is 86.6 m
Part A: 5 is the coefficient, w is the variable, 50 is the constant
Part B: 10 x 5 = 50 + 2 x 20 = 40+ 50 = $140
Part C: the constant,50,would change and become 85. Hope this helps :)
You can buy 50 of the cherry candies with all of the 25$ because you do 25 divided by 0.50 and get 50 and then if you would like to check that do 50 x 0.50 and you will still get 25$
