Two boats A and B Left a Port at the same time on different routes . B travelled on a bearing of 150º and A travelled on the Nor

adell [148]

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°.

What is a solution set 3x - 10> 20

uysha [10]

The solution set is $x>10$

Explanation:

The equation is $3 x-10>20$

We need to determine the solution set of the equation by finding the value of x.

Hence, the solution can be determined by solving the inequality for x.

Thus, Adding both sides of the inequality by 10, we get,

$3x-10+10>20+10$

Simplifying the inequality, we get,

$3x>30$

Now, dividing both sides of the inequality by 3, we have,

$\frac{3x}{3} >\frac{30}{3}$

Simplifying the inequality, we get,

$x>10$

Solution set is $x>10$

Thus, the solution set is $x>10$
