Answer:
Step-by-step explanation:
In any triangle, the cosine/cos of an angle is equal to its adjacent side divided by the hypotenuse (longest side) of the triangle. (a/h)
The angle marked 40 degrees has an adjacent side of and the hypotenuse of the triangle is 60.
Therefore, we have the equation:
Answer:
Step-by-step explanation:
Hello,
Thanks
We can use the Сosine formula to solve this problem.
<span>First we must find the third side (АС) of the triangle:
</span>
<span>
The smallest angle of the triangle lies opposite the smallest side, so we need to find m</span>∠C.
Now we can use Bradis's Table (I don't know the name in English, maybe Trigonometric Table?) to find m∠C:
m∠С = 38°42' = 38.7°
Answer: 38.7°
<span>I hope this helps</span>
