A person standing d=145 centimeters from a mirror notices that the angle of depression from his eyes to the bottom of the mirror is a=14 degrees, while the angle of elevation to the top of the mirror is b=11 degrees. Find the vertical dimension of the mirror

The length of the mirror is 64.52 cm

Explanation:

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

i got 142 as my answer

step-by-step explanation:

hello from mrbilldoesmath!

answer:

the domain is the set { -2, 0, 2, 3}

discussion:

the domain is the set of x values in the ordered pairs (x,y). taking the x, or first component, of each ordered pair gives   -2, 0, 2, 3.
