Find the reference angle of the following angles:

7π/18 radians

Step-by-step explanation:

A reference angle for angle β is the positive acute angle made by the terminal side of angle β and the x-axis.

A semi-circle angle has a measure of π radians.

The angle of the figure (in absolute value) can be decomposed as the addition of its reference angle and π radians. Therefore:

π + reference angle  = 25π/18

reference angle  = 25π/18 - π

reference angle  = 7π/18 radians

1)is not similar since corresponding sides are not in the same ratio

2)are similar since corresponding sides are in the same ratio and corresponding angles are equal

hope it will
