Answer:
B
Step-by-step explanation:
Answer:
Infinite solutions
Step-by-step explanation:
5(-3x-2)-(x-3)=-4(4x+5)+13
-15x-10-x+3=-16x-20+13
-16x-7=-16x-7
-16x=-16x
-x=-x
x=x
There are infinite many solutions
Answer: 67.2°
Step-by-step explanation:
To find angle C, we have to use cosine rule. Therefore,
12² = 8² + 10² - 2 × 8 × 10 × cosC
C = 82.8°
The bearing of A from C will be
= 150° - 82.8°
= 67.2°.
