Question

two angles of a triangle are in the ratio 2-3 and its third angle is 80° find the other two angles of the triangle ​

Answer 1

Answer:

first angle is 40

second angle is 60

Step-by-step explanation:

2x+3x+80=180°

5x=100

x=20

2x=40

3x=60

Answer 2

Answer:

• 40° and 60°

Step-by-step explanation:

It's given that two angles of a triangle are in the ratio 2 : 3 and its third angle is 80°

To Find : other two angles

Let first angle be 2x and second be 3x.

We know that Angle sum property of the triangle states that the sum of the angles of triangle is 180°

2x + 3x + 80° = 180

5x + 80° = 180

5x = 180 - 80

5x = 100

x = 100/5

x = 20

Hence,

First angle = 2x

= 2 × 20

= 40°

Second angle = 3x

= 3 × 20

= 60°

Therefore the other two angles of the triangle are 40° and 60°.
