Answer:
Acute angle, right angle, obtuse angle and reflex angle.
Step-by-step explanation:
Acute angle -
0° < θ < 90°
Right angle -
θ = 90°
Obtuse angle -
90° < θ < 180°
Reflex angle -
θ > 180°

</span>formula for the nth term is;
<span>2n^2 + 3n - 10</span>
We know that
the angle MOP is equal to arc MNP because is a central angle
the answer is
angle MOP=126°
So,

Multiply both sides by 11.

Divide both sides by 7.
f = 1
