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
3/4z = 2/3a
z + a = 510...z = 510 - a
3/4(510 - a) = 2/3a
382.50 - 3/4a = 2/3a
382.50 = 2/3a + 3/4a
382.50 = 8/12a + 9/12a
382.50 = 17/12a
382.50 * 12/17 = a
270 = a
z + a = 510
z + 270 = 510
z = 510 - 270
z = 240
check..
3/4z = 2/3a
3/4(240) = 2/3(270)
180 = 180 (correct)
Zul had $ 240
Zul gave 30% of his money to his sister
0.30(240) = 72
his sister received $ 72
