Question

Q6- The angles of a triangle are in the ratio 1:4:7. find the measures.

pls tell me step by step pls.... anyone tell me..​

Answer 1

Step-by-step explanation:

(let the angles of the triangle be 1x,4xand 7x)

so, a triangle has 180° measure.

therefore,1x+4x+7x=180°

so,12x=180°

x=180÷12

x=15

now actual values of them are :-

1×15=15°

4×15=60°

7×15=105°

this is your final answer thanks

Answer 2

Let the common factor be x

Ratio = 1 : 4 : 7

The sum of the angles of a triangle is equal to 180 degree

hence,

1x + 4x + 7x = 180

12x = 180

x = 180/12

x = 15

therefore the ratio will be =

1 multiplied by 15 that is 15

4 multiplied by 15 that is 60

7 multiplied by 15 that is 105

Final answer = 15 : 60 : 105
