Magnitude 29891

The triangle ABC is the magnitude of the inner angle α 12 ° smaller than the angle β, and the angle γ is four times larger than the angle α. What size are these interior angles in the triangle?

Final Answer:

α =  28 °
β =  40 °
γ =  112 °

Step-by-step explanation:

α=β12 γ = 4 α α+β+γ=180  (β12)+β+4 α=180  (β12)+β+4 (β12)=180  6β=240  β=6240=40  β=40  α=β12=4012=28
γ=4 α=4 28=112
