Abcd is a rhombus find the measures of < 2 and < 3, if m < 1=22

Angle 2 = 22 degrees (that line is dividing that angle into 1 & 2 equivalently)

Angle 3 = 90 degrees.

Ithink is a. true, but not sure

Hello! i hope this
since the cosine is the ratio of the adjacent side to the hypotenuse, you can see that cos 60° = ½. answer. according to the property of cofunctions (topic 3), sin 30° is equal to cos 60°. sin 30° = ½.
