Question

5. If the angles of a triangle are in the ratio 2:3:4,
determine the three angles.​

Answer 1

Step-by-step explanation:

2x+3x+4x=180

9x=180

x=20

so angles are 40,60and80

Answer 2

$\huge\mathtt{{\colorbox{silver}{★ANSWER★}}}$

Let us consider the the angles of the triangle to be 2x, 3x and 4x

We know that the sum of the angles of the triangle is 180°

Therefore,

180° = 2x + 3x + 4x

= 180° = 9x

= 20° = x

Therefore the three angles are,

2x = 40°

3x = 60°

4x = 80°
