Question

b+1 and b-1 are 5he side of right triangle find the other side​

Answer 1

Answer:

according to Pythagorean theorem

${(ab)}^{2} + {(bc)}^{2} \: = \: {(ca)}^{2}$

Step-by-step explanation:

${(b + 1)}^{2} + {(b - 1)}^{2 } = \: {b}^{2} + 1 + 2b + {b}^{2} + 1 - 2b \: = \: 2( {b}^{2} + 1)$

(ab) = b+1 , (bc)=b-1

to find ca

${(ca)}^{2} \: = \: 2( {b}^{2} + 1) \\ ca \: = \: \sqrt{2({b}^{2} + 1)}$
