yan [13]3 years ago
5 0

Answer:

Add 22/63

Step-by-step explanation:

3/7 + n = 7/9

<u>Step 1:  Subtract 3/7 from both sides</u>

3/7 + n - 3/7 = 7/9 - 3/7

n = 49/63 - 27/63

n = 22/63

Answer:  Add 22/63

A person standing d=145 centimeters from a mirror notices that the angle of depression from his eyes to the bottom of the mirror
Serggg [28]

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:

tan(11) = \frac{AB}{BO}\\ \\0.195 = \frac{AB}{145} \\\\AB = 28.275 cm

For the angle of depression:

tan(14) = \frac{BC}{BO} \\\\0.25 = \frac{BC}{145} \\\\BC = 36.25 cm

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
