Question

In right angle abc,angle B=90degress ab=1.6,bc =2.8 find ac

Answer 1

answer is 3.22=ac

good question

have a nice day

Answer 2

Step-by-step explanation:

by pythagoras theorem

ac2=ab2+bc2

=(1.6)2+(2.8)2

=2.56+7.84

=10.4

ac =

$\sqrt{104 \div 100}$

ac=

$\sqrt{2 \times 52 \div 10 {}^{2} }$

ac=

$10 \sqrt{2 \times 2 \ \times 2 \times 13}$

ac=

$10 \times 2 \sqrt{13 \times 2}$

ac=

$20 \sqrt{26}$
