Right triangle calculator

The right triangle calculator finds the missing area, angle, leg, hypotenuse and height of a triangle. The calculator also provides steps on how to solve the most important right triangles: the 30-60-90 triangle and the 45-45-90 triangle.

Find two sides of a triangle ABC if hypotenuse c= $ \frac{ 69 }{ 10 }$ .

solution

Shorter leg $ a = \dfrac{ 69 }{ 20 } $

Long leg $ b = \dfrac{ 69 \sqrt{ 3}}{ 20 } $

explanation

Step 1: Find short leg a

From the diagram above we can see that $ c = 2 \cdot a $. In this example we have:

$$ \begin{aligned} c &= 2 \cdot a \\[1.3 em] \frac{ 69 }{ 10 } &= 2 \cdot a \\[1.3 em] a &= \dfrac{ \frac{ 69 }{ 10 } }{ 2} \\[1.3 em] a &= \frac{ 69 }{ 20 } \end{aligned} $$
