Triangle angles

The arm is five times longer than its base in an isosceles triangle. Calculate its interior angles.

Final Answer:

A =  84.2608 °
B =  84.2608 °
C =  11.4784 °

Step-by-step explanation:

r=5 b=1 p=(b/2)/r=(1/2)/5=101=0.1 A=180/π arccos(p)=180/3.1416 arccos(0.1)=84.2608=84°1539"
B=A=84.2608=84.2608=84°1539"
C=180(A+B)=180(84.2608+84.2608)=11.4784=11°2842"
