The best estimate is 478,000,000 x 2,500,000
we can see that
Z , L and S are three points of line ZS
so, Z , L and S are collinear
and
Z , L and S lie on plane M
so, they are coplanar
so, option-C....................Answer
THERE ISN'T AN EQUIVALENT ANSWER THERE IS A REMAINDER AND IT IS VERY LONG.
The length of the mirror is 64.52 cm
<u>Explanation:</u>
Given:
Distance of the person from the mirror = 145cm
Angle of depression = 14°
Angle of elevation = 11°
Vertical dimension of the mirror = ?
For angle of elevation:

For the angle of depression:

Total length of the mirror, AC = AB + BC
= 28.275 + 36.25cm
= 64.52 cm
Therefore, the length of the mirror is 64.52 cm
