Find the angle, in degrees between 0 and 360∘, which intersects the unit circle at the point (−1/2,3/√2).

it approx 103.2 degree

Step-by-step explanation:

s=90+tan^-1(1÷3√2)

I add 90 base on the coordinate , taking the centre of the circle place at origin

last option

step-by-step explanation:

given that δdef is right and isoceles,

assuming that side df is the hypotenuse means that de an ef are the other 2 sides that intersect at 90° and are of equal length.

because they are of equal length, we can say that they are congruent

because they intersect at 90°, their slopes must be opposite reciprocals.

only the last option satisfies these conditions.

associative property hopes this ! : )
