Question

in a triangle pqr, angle p =90 , angle q ,arrange the sides of triangle in ascending order of magnitude

Answer 1

Step-by-step explanation:

Let one angle of a triangle be x.

Second angle will be x+10.

Third angle will be x+20.

Using theorem, Sum of interior angles of a triangle is 180o .

 Hence ∠A+∠B+∠C=180o 

⇒x+x+10+x+20=180o

⇒3x+30=180o

⇒x=50o

∴ Angles are 50o,60o,70o.
