Question

The angles of a triangle are in the ratio 1 : 1 : 2. What is the largest angle? ​

Answer 1

Answer:

$\color{blue}sum \: of \: angles \: of \: triangle = 180 \degree \\ \color{blue}x + x + 2x = 180 \degree \\ \color{blue} 4x = 180 \degree \\ \color{blue} \boxed{ \boxed{x = 45 \degree}} \\ \color{orange}angle \: 1 = angle \: 2 = x= 45 \degree \\ \color{orange} angle \: 3 = 2x = 90 \degree \\ \\\red{\mathfrak{ \large{\underline{{Hope \: It \: Helps \: You}}}}} \\ \blue{\mathfrak{ \large{\underline{{Mark \: Me \: Brainliest}}}}}$

Answer 2

Answer:

1 : 1 : 2=180°[Sum of 3 sides of a triangle=180°]

let the ratio be x:x:2x

x+x+2x=180°

4x=180°

x=180°/4

x=45°
