Consider a right angle triangle ABC. The hypotenuse AC is equal to 27 and base AB is equal to 13. Then according to Pythagoras theorem;

AC2 = AB2 + BC2

BC2= AC2 - AB2

BC2= 272 - 132

BC2= 729 - 169

BC2= 560

BC= 23.66

Angle B is 90o then angle A and angle C are;

CosA= AB/Ac


A= because-1[13/27]

A= 61.22o

As we know;

A + B + C = 180o

61.2 + 90 + C=180

C= 28.78o
