The inverse value of sin⁻¹(A) = Ф° , is sin(Ф) = A
sin(Ф°) = (-√3)/2 THAT MEANS Ф = -60° OR Ф = 300°
103 or 135 I’m not really sure which one
The correct answer is: <span>180°
Explanation:
Let's consider each angle one by one:
</span><span>45°: If we rotate the above figure by </span>45°, it will not map onto itself; rather it will make <span>45° angle with the correct figure.
</span>90°: If we rotate the above figure by 90°, it will be perpendicular to the given figure.
180°: If we rotate the above figure by 180°, it will map onto itself exactly.
360°: If we rotate the above figure by 360°, it will map onto itself exactly.
However, as the question is about the least angle, hence, in this case, the correct answer is 180° (since 180° < 360°).
Answer:
31/55 × 111
Step-by-step explanation:
the first one is less than 111 because it contains the only fraction that is less than 1
31/55 equals about 0.56
55/55 = 1
55/31 equals about 1.77
31/31 = 1
6x^2 - 8 = 4x^2 + 7x
6x^2 - 4x^2 - 7x - 8 = 0
2x^2 - 7x - 8 = 0
discriminant = b^2 - 4ac; where a = 2, b = -7 and c = -8
d = (-7)^2 - 4(2)(-8)
d = 49 + 64
d = 113
the discriminant is greater than zero, so there are two real roots
