How do you write an exact angle measure without approximating to a decimal value?

an exact angle measure without approximating to a decimal value is given below.

Step-by-step explanation:

Since an angle of 2 has degree measure 360° it follows that an angle of 1 radian has degree measure (180/ )°. Likewise, an angle of size 1° has radian measure /180. We now can easily obtain a formula to convert from degrees to radians and vice-versa. To convert from degrees to radians, multiply the angle by /180.

convert decimal degrees to DMS :

v: l•w•h÷2.

v: 20•6•8 ÷2

v: 960÷2

v: 480

25.2

step-by-step explanation:

2+4x6-8/10= 25.2
