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.

special triangle 45-45-90
Find two sides of a triangle ABC if leg a= $ \frac{ 93 }{ 10 }$ .

solution

Leg $ b = \dfrac{ 93 }{ 10 } $

Hypotenuse $ c = \dfrac{ 93 \sqrt{ 2}}{ 10 } $

explanation

Step 1: Find hypotenuse c.

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

$$ c = \sqrt{2} \cdot \frac{ 93 }{ 10 } = \frac{ 93 \sqrt{ 2}}{ 10 } $$

Step 2: Find leg b.

From the diagram above, we can see that $ b = a = \frac{ 93 }{ 10 } $.
