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°

Answer: Option 3
Step-by-step explanation:
You can make equivalent fractions by multiplying or dividing both top and bottom by the same amount. You only multiply or divide, never add or subtract, to get an equivalent fraction.
I hope this helps.
Answer:
There are multiple possibilities. One is there are 12 boys, and 16 girls. 12+16= 28 which is between 20 and 30. That would be 12:16, which can be simplified to 3:4. There is also 9 boys, and 12 girls. that would be 9:12, which can be simplified to 3:4. Also, 9 + 12 = 21, which is between 20 and 30.
The required length of the hypotenuse of the triangle is √19.
<h3>
What is a right triangle?</h3>
- A right triangle, sometimes known as a right-angled triangle, or more formally an orthogonal triangle, formerly known as a rectangle triangle, is a triangle with one right angle or two perpendicular sides.
To find the required length of the hypotenuse of the triangle:
Legs in the right triangle refer to the perpendicular and base.
Hypotenuse:
Therefore, the required length of the hypotenuse of the triangle is √19.
