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°
Answer:
I think it is 37.5°.
Step-by-step explanation:
By cross-multiplying, we get
15x + 30 = 24
15x = -6
x = -3 / 5
The answer is n = d/4 + 1/2
