Answer 2

★Given that an angel in a isosceles triangle measures 100°,find the other two congruent angles.

__________________________________________

now, the sum of interior angles in a triangle = 180°

so,let the other two angles be x

${\pink{\sf{⟹100 + x + x = 180}}} \\{\sf⟹100 + 2x = 180 } \\{\sf⟹ 2x = 180 - 100} \\ ⟹2x = 80 \\{\blue{\sf{ ⟹x = 40}}}$

$\therefore {the \:measure \:anglex=40°}$

hope this helps.!
