Answer:

So the value of u is [tex]24[/tex] degree.

Step-by-step explanation:

Given;

Three angle [tex]2u[/tex] , [tex](u+18)[/tex] degree and [tex]90[/tex] degree in a Triangle.

We know;

Addition of three angle in a triangle is equal [tex]180[/tex] degree

[tex]2u+u+18+90=180[/tex]

[tex]3u=180-90-18[/tex]

[tex]3u=72[/tex]

[tex]u=\frac{72}{3}[/tex]

[tex]u=24[/tex]

∴ The value of u is [tex]24[\tex] degree.
