Question

the angles of triangle are in ratio 3:4:5. Find the angles​

Answer 1

Answer:

3x+4x+5x=180

12x=180

x=180/12

×=15

3x=45

4x=60

5x=75

So,the angles are 45,60 and 75.

Answer 2

Step-by-step explanation:

first angle of triangle 3x

second angle of triangle 4x

third angle of triangle 5x

we all know that the sum of three angles of triangle is 180 so

3 X + 4 x + 5 x =180

12x=180

x=180/12

x=15

to find the angles X 345 with the value of x
