# Base

Compute base of an isosceles triangle, with the arm a=20 cm and a height above the base h=10 cm.

Correct result:

b =  34.64 cm

#### Solution:

$(b/2)^2 = 20^2 - 10^2 \ \\ \ \\ b = 2 \sqrt{ 20^2 - 10^2} = 34.64 \ \text{cm}$ Our examples were largely sent or created by pupils and students themselves. Therefore, we would be pleased if you could send us any errors you found, spelling mistakes, or rephasing the example. Thank you!
