May I have some help with this?​

a. tanB= 3/2

Step-by-step explanation:

tanA= p/b =:2/3

For angle A,

p= 2

b=3

For angle B,

p = 3

b=2

So, TanB = 3/2

9514 1404 393

  42.0°

Step-by-step explanation:

To compute the angle, we need the measures in compatible units. It can be convenient to convert feet to meters.

  Tan = Opposite/Adjacent

  tan(angle of elevation) = (building height)/(shadow length)

  angle of elevation = arctan((62 ft)(0.3048 m/ft)/21 m) = arctan(18.8976/21)

  angle of elevation ≈ 41.984°

The angle of elevation of the sun is about 42.0°.
