Circumferential angle

Vertices of the triangle ΔABC lay on the circle and are divided into arcs in the ratio 7:8:7.

Determine the size of the angles of the triangle ΔABC.

Correct answer:

A =  57.27 °
B =  65.45 °
C =  57.27 °

Step-by-step explanation:

x=7+8+7180=11908.1818  A=7 x=7 1190=117 90=11630=11630=57.27=57°1622"
B=8 x=8 1190=118 90=11720=11720=65.45=65°2716"
C=7 x=7 1190=117 90=1163057.2727   Verifying Solution:   s=A+B+C=11630+11720+11630=11630+720+630=111980=180
