Right angle

If a, b and c are two sides of a triangle ABC, a right angle in A, find the value on each missing side. If b=10, c=6

Result

a =  11.662

Solution:

b=10 c=6 a2=b2+c2 A=90∘=>a>b>c  a=b2+c2=102+62≐2 34≐11.6619≐11.662b=10 \ \\ c=6 \ \\ a^2=b^2+c^2 \ \\ A=90^\circ => a>b>c \ \\ \ \\ a=\sqrt{ b^2+c^2 }=\sqrt{ 10^2+6^2 } \doteq 2 \ \sqrt{ 34 } \doteq 11.6619 \doteq 11.662
