The angles 4

The angles of a triangle are divided into the ratio 126: 213: 312. If the three angles sum to 180°, find the size of each of the three angles.

Correct answer:

α =  34.8387 °
β =  58.894 °
γ =  86.2673 °

Step-by-step explanation:

α:β:γ=126:213:312  d=126+213+312180=217600.2765   α=126 d=126 0.2765=34.8387=34°5019"
β=213 d=213 0.2765=58.894=58°5338"
γ=312 d=312 0.276586.2673   Verifying Solution:  s=α+β+γ=34.8387+58.894+86.2673=180
