<span>arctan(2x) = -1 radian
</span>⇒ 2x = tan(-1)
⇒ 2x = -1.5574
⇒ x = -1.5574/2
⇒ x = - 0.7787<span>

Answer:
2/3
8/12
Step-by-step explanation:
You just divide each numerator 4 (5÷4) and each denominator by 6 (8÷6) and see if the numbers are the same.
5÷4=1.25
8÷6=1.33
They are not equivalent, so 5/8 is not correct
2÷4=0.5
3÷6=0.5
They are equivalent, so 2/3 is correct

Answer:
B
Step-by-step explanation:
In an isosceles trapezoid any lower base angle is supplementary to any upper base angle, thus
6x + 2x + 4 = 180, that is
8x + 4 = 180 ( subtract 4 from both sides )
8x = 176 ( divide both sides by 8 )
x = 22 → B
