Question

1. Find the radian measure for 150 degrees.
2. Find the degree measure for π/2.
Please explain how you used the unit circle to solve these questions.

Answer 1

Answer:

Step-by-step explanation:

1. 150 * π/180

= 150π/180

= 5π/6

=2.62

2. π/2

π/2 * 180/π

= 90 degrees

Answer 2

Step-by-step explanation:

1)150° 's radian measure

$\rm \implies150 \: Deg × π/180 = 2.618 \: Radians$

2)π/2 's degree measure

$\rm \: \implies \: π/2 × 180/π= 180/2 = 90 \: degrees$

Basically,we need to use formulas to solve these type of sums.
