**Byebyebimari**

The hypotenuse is always opposite the right angle and it is always the longest **side** of the **triangle**. To find the length of **leg** a, substitute the known values into the Pythagorean Theorem. Solve for a^{2}.

.

In respect to this, how do you find the long leg of a triangle?

You can multiply the short side by the square root of 3 to **find** the **long leg**. Type 2: You **know the** hypotenuse. Divide the hypotenuse by 2 to **find** the short side. Multiply this answer by the square root of 3 to **find** the **long leg**.

Also Know, how do you find the missing angle of a triangle given two sides? **Example**

- Step 1 The two sides we know are Opposite (300) and Adjacent (400).
- Step 2 SOHCAHTOA tells us we must use Tangent.
- Step 3 Calculate Opposite/Adjacent = 300/400 = 0.75.
- Step 4 Find the angle from your calculator using tan
^{–}^{1}

One may also ask, how do you find a missing angle?

To determine to measure of the unknown **angle**, be sure to use the total sum of 180°. If two **angles** are given, add them together and then subtract from 180°. If two **angles** are the same and unknown, subtract the known **angle** from 180° and then divide by 2.

How do you find the missing angle in an isosceles triangle?

If you are given one interior **angle of an isosceles triangle** you can **find** the other two. For example, We are given the **angle** at the apex as shown on the right of 40°. We know that the interior **angles** of all **triangles** add to 180°. So the two base **angles** must add up to 180-40, or 140°.
