Answer:
An equation is [tex]x+52\°+90\°=180\°[/tex]
Step-by-step explanation:
Let [tex]x[/tex] be the measure of the unknown acute angle.
According to angle sum property of a triangle, sum of all the angles of a triangle is equal to 180°.
One of the acute angles of a right triangle is equal to 52°.
Also, the triangle is a right angled triangle, one of the angle must be equal to 90°.
[tex]x+52\°+90\°=180\°\\x+142\°=180\°\\x=38\°[/tex]
So, an equation is [tex]x+52\°+90\°=180\°[/tex]
