Question

please help me answer this

Answer 1

Answer:

a=√89 ,b=√289-144=√145

Answer 2

Answer:

In triangle 1,

By Pythogoras Theorem,

Formula

${8}^{2} + {5}^{2} = {a}^{2}$

Hence by calculation,

a = √ 64 + 25

= √89

In triangle 2,

Similarly by Pythogoras Theorem

${12}^{2} + {b}^{2} = {17}^{2}$

Hence by calculation,

b = √289 -144

= 145

b= √145
