Question

In a rhombus ABCD, m∠A = 31°. Point O is a point of intersection of diagonals. Find the measures of the angles of triangle ΔBOC.

Answer 1

m∠ COB= 90 degrees

m∠OBC = 74.5 degrees

m∠OCB = 15.5 degrees

Explanation:

If you do RSM don't forget to put in the degrees symbol

Answer 2

∠BOC = 90 degrees, ∠OCB = 15.5 degrees, ∠OBC = 74.5 degrees
