Given parameters:
Quadratic expression:
x² - 6x + 7 = 0
Solve using quadratic formula;
x =
From the equation;
a = 1, b = -6 and c = 7
Input the parameters and solve;
x =
x =
x =
x = or
x = 7 or -1
I multiplied the dimensions and divided it by 75, got 8.75 but you need to round in this situation, so 9
hope this helps :)
The equation is the given one:
Which is the same as:
And the interval of the angle θ must be (0°,90°) so, 2θ must be (0°,180°).
So the statement is True.
