Find all solutions in the interval 0° ≤ 𝜃 < 360°. If rounding is necessary, round to the nearest tenth of a degree.

Question

2 sin 𝜃 − 2=0

Answer 1

2 sinx - sqrt(2) - 0

sinx = sqrt(2)/2

sin is positive in 1st and 2nd quadrants and above is true when reference angle is 45 degrees

x = 45 and 135 degrees
