Question

The hypotenuse of a right triangle is 13cm.if one of the remaining two sides is of length 5 Cm,measure the length of the third side by constructing the triangle

Answer 1

by Pythagoras theorem

h^2=b^2+p^2

(13)^2=(5)^2+p^2

169=25+p^2

169-25=p^2

144=p^2

√144=p

p=12

Answer 2

USING PYTHAGORAS THEOREM

${13}^{2} = {5}^{2} + {x}^{2}$

169 = 25 + x^2

${x}^{2} = 144 \\ x = 12$

this is your answer
