| It is known from the condition that one of the angles of the rhombus is 136 °. We need to find the value of the acute angle of the rhombus.
We start by denoting the degree measure of the smaller angle as x °.
Let’s also apply the properties of the rhombus corners – the opposite corners of the rhombus are equal to each other.
That is, a rhombus has two 136 ° angles and two x ° angles.
The sum of the angles of a rectangle is 360 ° (a rhombus is also a rectangle).
We get the equation:
136 * 2 + 2 * x = 360;
272 + 2x = 360;
2x = 360 – 272;
2x = 88;
x = 44 ° two sharp corners.
Answer: 44 °.
