IS triangle

Calculate interior angles of the isosceles triangle with base 46 cm and legs 49 cm long.

Result

α = β =  62 °
γ =  56 °

Solution:

α=β=arccos(46249)=62\alpha = \beta = \arccos( \dfrac{ 46 }{ 2 \cdot 49} ) =62 ^\circ
γ=2arcsin(46249)=56\gamma = 2 \arcsin( \dfrac{ 46 }{ 2 \cdot 49} ) =56 ^\circ
