Question

the measures of three angle of a triangle are in the ratio 1:2: 3then the triangle is​

Answer 1

$\begin{gathered}{\underline{\underline{\maltese{\Huge{\textsf{\textbf{\red{Answer: }}}}}}}}\end{gathered}$

Let 1st angle be x

Second angle be 2x

And, third angle be 3x

Then,

x+2x+3x = 180°

6x = 180°

x = 180°/6

=> x = 30°

So, first angle = x = 30°

Second angle = 2x = 2×30° = 60°

Third angle = 3x = 3×30° = 90°

Since, the triangle is right angled triangle.

Answer 2

Step-by-step explanation:

Let 1st angle be x

Second angle be 2x

And, third angle be 3x

Then,

x+2x+3x = 180°

6x = 180°

x = 180°/6

=> x = 30°

So, first angle = x = 30°

Second angle = 2x = 2×30° = 60°

Third angle = 3x = 3×30° = 90°
