Question:

In Example 3, change 53´ to 35´ and then find the decimal form.

Data from Example 3

(a) We change 17°53´ to decimal form by using the fact that 1° = 6´. This means that 53 = (53/60)° = 0.88° (to nearest 0.01°). Therefore, 17°53´ = 17.88°. See Fig. 4.6.

(b) The angle between two laser beams is 154.36°. To change this to an angle measured to the nearest minute, we have 0.36° = 0.36(60´) = 22´ This means that 154.36° = 154°22´. See Fig. 4.7.
