Answer:
(-1, -1)
Step-by-step explanation:
One way to write the relationship between the x and y coordinates and θ is ...
tan(θ) = y/x
Then ...
y = x·tan(θ) = -1·tan(-3π/4) = -1·1
y = -1
The coordinates of the point on the terminal side are (x, y) = (-1, -1).
Answer:
18.4 , 1.84, 3.68, 0.368
Step-by-step explanation:
I I could be completely wrong I've never done this before but I believe the numbers are doubled (multiplied by 2) then divided by 10.
Hope this helps!

Answer:
a = 4
Step-by-step explanation:
Assuming you require to find the value of a
In a rhombus all the sides are congruent, thus
9a - 13 = 3a + 11 ( subtract 3a from both sides )
6a - 13 = 11 ( add 13 to both sides )
6a = 24 ( divide both sides by 6 )
a = 4
Then
XW = 9a - 13 = 9(4) - 13 = 36 - 13 = 23
Thus the sides of the rhombus are 23 units
