Answer:
1.) 18°
2.) 108°
3.) angle r = 60°, while angle n = 120°
Step-by-step explanation:
1.) complentary = 90°
90 = 72 + ?
<? = 90 - 72
<? = 18
2.) supplement = 180°
180 = 72 + ?
<? = 180 - 72
<? = 108°
3.) Let's use r as the first angle, and n be the second angle
r + n = 180°
r = 2n
2n + n = 180°
3n = 180°
r = 60°
n = 2y = 2(60°) = 120°
