Answer:

$m\angle A = 98$

Explanation:

Since it's a triangle all it's interior angles sum up to 180°

The triangle is isosceles which means two of it's angles are equal

From the question

$m\angle B = m\angle C = 41 \degree$

So to find
$m \angle A$ add up all the angles and equate it to 180° and solve for A

That's

$m\angle A + m\angle B + m\angle \: C = 180 \\ m\angle A = 180 -m\angle B - m\angle \: C \\ m\angle A = 180 - 41 - 41 \\ = 180 - 82$

We have the final answer as

$m\angle A = 98$

Hope this helps you
