Theta has a reference angle of 30° and is in Quadrant I or II.
Sin(theta) = ½
Basic angle: 30
<h3>What is the reference angle?</h3>
The acute angle between the terminal arm/terminal side and the x-axis. The reference angle is always positive. In other words, the reference angle is an angle sandwiched between the terminal side and the x-axis.
Angles: 30,
180-30 = 150
Because sin is positive in quadrants 1 and 2.

Step-by-step explanation:
A right triangle has to have one angle equal to 90 degrees. All isosceles triangles are equilateral. The only requirement for an isosceles triangle is for at minimum 2 sides to be the same length. An isosceles triangle can have more than 2 sides of the same length, but not less.
