We have that
the measure of angle ∅=7*pi/6
the measure of its reference angle is?
remember that pi=180°
then
7*pi/6=7*180/6=210°------------> III Quadrant
Part A) its reference angle is 210°-180°=30°
Part B) sin(30°)=-0.5--------> negative because belongs III quadrant

Answer:
2.a)31°
b)135°
3.a)72°
Step-by-step explanation:
2a) Angles in a straight line add up to 180°
180-62=118°
since in an isosceles triangle base angles are equal 62÷2=31°
b)sum of interior angles=180(n-2)
180(8-2)=1080°
each angle is 1080÷8=135°
3.a) Exterior angle=360/n
=360÷5=72° each
