A coterminal angle of θ such that 0 ≤ θ ≤ 2π is equal to 7π/4 and the exact value of Sin(θ) = -1/√2.
<h3>What is a coterminal angle?</h3>
A coterminal angle can be defined as an angle that share the terminal side of an angle which occupies the standard position i.e it has the same initial side.
In this scenario, all angles that are multiples of 2π and added to the given angle (-9π/4) would be coterminal. For the range [0, 2π], 8π should be added to the given angle as follows:
Coterminal angle = -9π/4 + 4π
Coterminal angle = -9π/4 + 16π/4
Coterminal angle = 7π/4.
<h3>Part B.</h3>
The reference angle is given by:
7π/4 -π = 3π/4.
Therefore, the exact values of all six (6) trigonometric functions evaluated at θ are:

Answer: D
Step-by-step explanation:edge 2020
Hey there!
2(3x - 7) = 9y
2(3x - 7) = 9(-7)
2(3x - 7) = -63
2(3x) + 2(-7) = -63
6x - 14 = -63
ADD 14 to BOTH SIDES
6x - 14 + 13 = -63 + 13
SIMPLIFY IT!
6x = -63 + 13
6x = -49
DIVISION 6 to BOTH SIDES
6x/6 = -49/6
SIMPLIFY!
x = -49/6
x = -8 1/6
Therefore, the answer should be:
x = -8 1/6 (or x = -49/6 [EITHER OF THOSE SHOULD BE YOUR RESULT BECAUSE THEY ARE BOTH EQUAL TO EACH OTHER])
Good luck on your assignment & enjoy your day!
