Question

2. Find the third angle of a triangle if the measures of its angles are 40° and 100°.​

Answer 1

$\huge\boxed{\red{Answer :-}}$

Find the third angle of an isosceles triangle.

Here's how to find it: If one of the equal angles is 40°, then you'll know that the other angle is also 40°. You can find the third side, if needed, by subtracting 40° + 40° (which is 80°) from 180°. 180° - 80° = 100°, which is the measurement of the remaining angle.
