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
The perimeter of a triangle assuming that all the sides are the same, would be 3 multiplied by 28 to get 84. Since the perimeter of the square is the same, that would mean that 84 units is the total addition of the 4 sides of the square. So divide 84 by 4 to get the length of one side ( which is 24 units).
Finally, the area of a square is defined as two sides multiplied by each other, so 24 multiplied by 24.
Hope this helps.

hope this helps!! p.s. i really need brainliest :)
Answer:
17
Step-by-step explanation:
let x be the number of boxes to be shaded to make it 80%
x = 80% of total number
= 80/100 of 25
= 80/4
= 20
So 20 need to be shaded to fill 80%
Now, 13 of the grids are already shared so the amount of more squares that need to be shaded = 20-13
= 17 squares
