Complete question is;
Find the measures of a positive angle and a negative angle that are co-terminal with each given angle.
8. θ = -25°
9. θ = -390°
Answer:
8) Negative coterminal angle = -385°
Positive coterminal angle = 335°
9) Negative coterminal angle = -750°
Positive coterminal angle = 330°
Step-by-step explanation:
For us to find a positive coterminal angle, we add 360° to the given angle. Whereas to find the negative coterminal angle, we subtract 360 from the given angle.
Thus;
8) for θ = -25° ;
Negative coterminal angle = -25° - 360° = -385°
Positive coterminal angle = -25° + 360° = 335°
9) For θ = -390° ;
Negative coterminal angle = -390 - 360 = -750°
Positive coterminal angle = -390 + 360 = -30°
Since it's negative, we add 360 again till it's positive.
Thus = -30° + 360 = 330°
Answer:
38°
Step-by-step explanation:
∠4=∠2
∠2=∠6
∠6=38°
So ∠4=38°
Answer:
x=-8
Step-by-step explanation:
Subtract 2 from both sides
Simplify
Multiply all terms by the same value to eliminate fraction denominators
Cancel multiplied terms that are in the denominator
Subtract 2x from both sides
Simplify
Answer:
50.24 yards²
Step-by-step explanation:
The equation for area of circle is πr². So the calculation is 4² × 3.14.
16 × 3.14 = 50.24
Hello!
On the graph, when the X values are between 4 and 8, they are being constant. The X values between 4 and 8 are constant because the line shown between 4 and 8 on the graph show the line as a straight line. It is not going up nor is it going down, so you can conclude that the X values are not increasing or decreasing.
I hope this helps!
