*flashbacks to honors trig in 9th grade*
...Anyway. We're given that the bearing from A to C is so that means that the <em>counterclockwise</em> angle from the north to C is Therefore,
Now, we apply the law of cosines:
Answer:
Im not entirely sure but i think that either a or d is correct
Step-by-step explanation:
hope this helps!
1. You have the following quadratic equation and to solve it, you must follow the steps below:
<span>
x</span>²<span>+3=9x
2. The form of the equation that you need to apply the quadratic formula, is:
ax</span>²+bx+c=0
<span>
3. Then:
</span>
x²<span>+3=9x
</span> x²-9x<span>+3=0
</span><span>
4. The quadratic formula is shown below:
x=(-b±√(b^2-4ac))/2a
5. Then, you have:
a=1
b=-9
c=3
6. When you substitute the values into the quadratic formula, you obtain:
x1=0.34
x2=8.65</span>
