49/56 in it's simplest form is 7/8.
(?) is (-1) and that gray blank thing is 3.
Give a brainliest please:-)
Is there supposed to be a picture?
Answer:
#5 :16.38
Step-by-step explanation:
perimeter:
length AB = 6-0 = 6
length BC = 
= 5.65685
length AC = 
= 4.4721
answeri = 6+ 5.65685 + 4.721 = 16.38
#6 the question didn't show fully,,
Answer:
(a) AC = 12.565 m
(b) bearing of C from A is 90°
(c) BT = 9.373 m
Step-by-step explanation:
(a) extend North line down & perpendicular to AC.
Call that perpendicular intersection "P".
∠BAC = 90° - 53° = 37°
cos 37° = AP/15
0.7986 = AP/15
AP = 11.979 m
∠PNC = 180° - 161° = 19°
∠BCP = 90° - 19° = 71°
18 cm = 0.18 m (red flag note: 18 cm looks very out of scale for the picture)
cos 71° = CP/0.18
0.3256 = CP/0.18
CP = 0.586 m
AC = 11.979 + 0.586 = 12.565 m
(b) The bearing to C from A is 90°
(c) tan 58° = 15/x
1.6003 = 15/x
x = 9.373 m
