How would I find the missing side of an obtuse triangle?

Using the pythagorean theorem ?

Try using the Law of Signs or the

Law of Cosines.

The law of what?

Yes, you can find the missing side of an obtuse triangle using the Pythagorean theorem. The Pythagorean theorem states that in a right triangle, the square of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the other two sides.

To find the missing side of an obtuse triangle, you'll need to first determine if it is a right triangle or not. If it is a right triangle, you can use the Pythagorean theorem directly. However, if it is not a right triangle, you'll need to create a right triangle by drawing an altitude or using some other method.

Once you have a right triangle, identify the two sides that you know the lengths of, and label them as 'a' and 'b'. The side you want to find is usually labeled as 'c' and represents the hypotenuse.

Then, you can apply the Pythagorean theorem, which is written as:

c^2 = a^2 + b^2

Simply substitute the known values for 'a' and 'b' into the formula and solve for 'c'. Take the square root of both sides to find the value of 'c'.

Keep in mind that if you are dealing with a decimal answer, round it to the appropriate number of decimal places based on the given measurements and the level of precision required.
