Express the angle in radian measure.60°

To express the angle in radian measure, we need to convert it from degrees to radians.

Step 1: Recall that there are π radians in 180 degrees.

Step 2: Set up a proportion to find the equivalent angle in radians.

180 degrees x radians ___________ = ___________ 1 π radians

Step 3: Cross multiply and solve for x.

180x = π

Step 4: Divide both sides by 180 to isolate x.

x = π/180

Therefore, the angle of 60 degrees is equivalent to π/180 radians.
