Question

How to solve this problem

Answer 1

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
