What is the minimum height of a planar mirror placed in a vertical plane 2m distant that will permit a person 2m tall to see themselves from head to toe?

Height of mirror will be 1 m for complete image of person

Explanation:

We have given distance of person from plane mirror d = 2 m

And height of person = 2 m

We have to find the height of plane mirror which given full image of person

Height of mirror will be equal to half of height of person

So height of mirror

So height of mirror will be 1 m for complete image of person

step-by-step explanation:

we are given

we have to simplify it

firstly, we will factor it

now, we can cancel like terms

now, we can combine it

so, we get

c. 7/3

step-by-step explanation:

a rational number is like pi- it is a repeating decimal.

a. is -1.8

b. 2.236068

c. 2.3333333333333333333

d.   is 3

i hope that ! =)
