Question

the angles of a triangle are in the ratio 1:2:3find the their measure state the type of angle​

Answer 1

By inspection of the ratio of angles, that's, 1:2:3, we can conclude, it is a right angle. (30°,60°,90°). Hope it help you

Answer 2

Ratio of angles =1:2:3

Let in the form of x= $1x:2x:3x$

$1x+2x+3x=180°\\6x=180°c\\x=\frac{180}{6}=30\\x=70$ [Angle sum property of a ∆]

$2x=2\times30\\=60\\\\3\times30\\=30$
