Answer:
∆pkl and ∆nkl
Step-by-step explanation:
Supplementary angles are two angles whose measures add up to 180° . The two angles of a linear pair , like ∠pkl and ∠nkl in the figure above, are always supplementary.
2,247
Step-by-step explanation:
take 3000 and minus that by 30 percent, then after that, add 7 percent to get your total.
A+30 = 60
a = 30
a + 2b = 60
30+2b = 60
2b = 30
b = 15
5b - 5c = 60
5(15) - 5c = 60
5c = 15
c = 3
10c + d = 60
10(3) + d = 60
30 + d = 60
d = 30
2d + 6e = 180 - 60
2(30) + 6e = 120
6e = 60
e = 10
4f + 4e = 120
4f + 4(10) = 120
4f = 80
f = 20
