How to solve this problem
Slav-nsk [51]

Answer:

8.95

Step-by-step explanation:

here we are going to use pythagoras theorem

a² +b² =c²

the vertical can be taken as a and horizontal as b

4² +8²=c²

this is the same as

c²= 4²+ 8²

c²= 16+ 64

c²=80

to get rid of the square we shall put both sides under a root

\sqrt{c ^{2} }  =  \sqrt{80}

c = 8.95
