Answer 1

Answer:

So the value of u is $24$ degree.

Step-by-step 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

$2u+u+18+90=180$

$3u=180-90-18$

$3u=72$

$u=\frac{72}{3}$

$u=24$

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