Answer:
re write it i dont get it
Step-by-step explanation:
Answer:
4) d = 60; e = 90
5) f = 30
6) h = 120
Step-by-step explanation:
4)
d + d + d = 180
3d = 180
d = 60
e + e + e + e = 360
4e = 360
e = 90
5)
70 + (180 - 100) + f = 180
70 + 80 + f = 180
f = 30
6)
45 + 75 + (180 - h) = 180
300 - h = 180
-h = -120
h = 120
