Answer:
a) acute angle
b) obtuse angle
c) right angle
d) reflex angle
e) straight line angle
f) acute angle
Step-by-step explanation:
Acute angle
- angle that is smaller than 90°
- 0° < θ < 90°
Right angle
- angle that is 90°
- shaped of a "L"
Obtuse angle
- angle that is greater than 90° but smaller than 180°
- 90° < θ < 180°
Straight line angle
- angle that is 180°
- drawn in a straight line
Reflex angle
- angle than is greater than 180°
- θ > 180°
Answer:
1st, 2nd, and last.
Step-by-step explanation:
For the first two common rules can be applied such as 
= ![\frac{\sqrt[n]{a} }{\sqrt[n]{b} }](https://tex.z-dn.net/?f=%5Cfrac%7B%5Csqrt%5Bn%5D%7Ba%7D%20%7D%7B%5Csqrt%5Bn%5D%7Bb%7D%20%7D)
and that ![\sqrt[n]{\frac{a}{b} } = (\frac{a}{b})^{n}](https://tex.z-dn.net/?f=%5Csqrt%5Bn%5D%7B%5Cfrac%7Ba%7D%7Bb%7D%20%7D%20%3D%20%28%5Cfrac%7Ba%7D%7Bb%7D%29%5E%7Bn%7D)
and for the last one this is just simplifying the radical and if you factor it you realize that, 
meaning that you can take the radical off of 5/8 and end up with that final answer

Answer:
- ∠ROK = 36°
- ∠CKO = 96°
- ∠C = 60°
Step-by-step explanation:
The same-side angles at each base are supplementary, so ...
∠ROC = 180° -120° = 60°
Because the trapezoid is isosceles, 60° also the measure of ∠C.
The angle sum theorem tells you ...
∠COK +∠ROK = ∠ROC
24° + ∠ROK = 60°
∠ROK = 36° . . . . . . subtract 24°
__
The sum of angles in ΔCKO is 180°, so ...
∠C +∠COK +∠CKO = 180°
60° +24° +∠CKO = 180°
∠CKO = 96° . . . . . . . . . . . . . subtract 84°
