Answer 2

Solution

Given :-

• ratio of three angle of triangle = 2:3:4

Find :-

• Largest angle of triangle

Explanation

We know,

Sum of all angle of triangle be = 180°

So, Acc. to question,

• first angle be = 2x
• second angle be = 3x
• Third angle be = 4x

So, Sum of all angle be = 180°

➡ 2x + 3x + 4x = 180°

➡9x = 180°

➡x = 180°/9

➡x = 20°

Hence

• First angle be = 2x = 2 × 20 = 40°
• Second angle be = 3x = 3×20 = 60°
• Third angle be = 4x = 4×20 = 80

Since

• Largest angle of triangle will be = 80°
