Question

the ratio of angles of a triangle is 2:3:7. express the angles in degree​

Answer 1

Answer:

30,45,105

Step-by-step explanation:

2p+3p+7p=12p=180

p=15

Answer 2

Answer: the angles are 30°, 45° and 105°

Step-by-step explanation:

Ratios of angles of triangle are 2:3:7

Let the angles be 2x , 3x and 7x

Sum of all angles in a triangle = 180

2x + 3x +7x = 180

12x = 180

x = 180/12

x = 15

first angle :

2x = 2 ( 15 )

= 30

2nd angle :

3x = 3 ( 15 )

= 45

3rd angle :

7x = 7 ( 15 )

= 105 ..

Hence, the angles are 30°, 45° and 105°
