Step-by-step explanation:
where is the question huh ?
In the rhombus, the diagonals are perpendicular.
We know, the sum of the measures of the triangle is equal 180°.
Therefore we have the equation:
![(2x-15)+3x+90=180](https://tex.z-dn.net/?f=%282x-15%29%2B3x%2B90%3D180)
<em>combine like terms</em>
![(2x+3x)+(-15+90)=180](https://tex.z-dn.net/?f=%282x%2B3x%29%2B%28-15%2B90%29%3D180)
<em>subtract 75 from both sides</em>
<em>divide both sides by 5</em>
![\boxed{x=21}](https://tex.z-dn.net/?f=%5Cboxed%7Bx%3D21%7D)
<h3>Answer: x = 21°</h3>
