The measure of angle 1 in the rhombus is determined as 74⁰.
How to calculate the measure of angle 1?
The measure of angle 1 is calculated by applying the following formula as shown below;
Each diagonal of a rhombus bisects the angle through which it passes.
Also, the opposite angles of a rhombus are equal.
The missing angles of the rhombus is calculated as follows;
(32 + 32) + 4(∠1) = 360 (sum of angles in a rhombus)
64 + 4∠1 = 360
4∠1 = 360 - 64
4∠1 = 296
∠1 = 296 / 4
∠1 = 74⁰
From the diagonal of the rhombus given, we calculated the value of angle 1 as ∠1 = 74⁰.
