Answer:
x = 14
Explanation:
The given figure is of the rhombus as all angle are equal.
Since the diagonal of a rhombus is a line segment that joins two non-adjacent vertices of the rhombus. A rhombus has two diagonals, which bisect each other at right angles.
By using this information:
We get
(5x + 20)° = 90°
5x + 20 = 90
Subtract 20 on both sides.
5x + 20 - 20 = 90 - 20
5x = 70
Divide both sides by 5.
x = 14
Therefore, the value of x is 14.
