Question

1. find the measure of ∠a. 35° 90° 35° 70° 55°

Explanation:

Step1: Recall properties of a rhombus

The diagonals of a rhombus are perpendicular bisectors of each other and also bisect the angles of the rhombus.

Step2: Use angle - bisecting property

The given angle of \(35^{\circ}\) and \(\angle A\) are part of the same vertex - angle of the rhombus and the diagonal bisects this vertex - angle. So \(\angle A = 35^{\circ}\).

Answer:

B. \(35^{\circ}\)
