Need help with this math problem

Answer 1

So the value of u is
`24` degree.

Explanation:

Given;

Three angle
`2u` ,
`(u+18)` degree and
`90` degree in a Triangle.

We know;

Addition of three angle in a triangle is equal
`180` degree

`2u+u+18+90=180`

`3u=180-90-18`

`3u=72`

`u=(72)/(3)`

`u=24`

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