so

Let

O——> the center of the rhombus

m∠AOB=

Remember that

The sum of the internal angles of a triangle is equal to

therefore

in the triangle AOB

m∠AOB+m∠OAB+m∠OBA=

substitute the values

solve for x

From the answer and question examples above, hopefully, they may help the student take care of the question they had been looking for and keep in mind of all sorts of things stated in the answer above. Then possibly will carry out some sharing in a group discussion and also study with the classmate relevant to the topic, so another student also own some enlightenment and still keeps up the school learning.
